Matthew 5

Today’s Passage: Matthew 5

The King has been announced, tested in the wilderness, and has begun to gather men to Himself, and now He sits down and opens His mouth, and what comes out is the longest stretch of His teaching that Matthew gives us. We call it the Sermon on the Mount. It runs for three chapters, and this first one is the foundation of everything that follows. It opens with nine pronouncements of blessing, and every one of them lands on a person the world would not have picked: the spiritually bankrupt, the grieving, the meek, the starving for righteousness, the merciful, the clean-hearted, the peacemakers, the hunted. Then the picture widens. Such people are salt in a decaying world and light in a dark one, a city that cannot be hidden, a lamp that was never meant for under a basket. Then comes the great hinge of the chapter, the statement that governs everything after it: He has not come to abolish the Law or the Prophets but to fulfill them, and the righteousness of His people must go beyond that of the professionals. And then, six times over, He takes a command everyone in the crowd had heard from childhood and drives it down to the root. Murder, back to anger. Adultery, back to the look. Divorce, back to the covenant. Oaths, back to a plain honest word. Retaliation, back to a heart that will absorb a wrong. Love of neighbor, stretched out to cover the enemy, because that is what the Father is like. And it closes on a summons that has stopped honest readers in their tracks for two thousand years.

As you read, hold this: The King came not to abolish the Law and the Prophets but to fulfill them, and He goes beneath every command to the heart it always addressed, pronouncing blessing on those the world overlooks and calling His people to a righteousness only He can create in them.

Matthew 5:1–2 (BSB)

¹ When Jesus saw the crowds, He went up on the mountain and sat down. His disciples came to Him, ² and He began to teach them, saying:

Two verses, and they set everything in order. Notice first what moves Him: “When Jesus saw the crowds.” He has just come through Galilee with the sick and the tormented pressing in on Him from every side, and the sight of them does not weary Him into silence. It opens His mouth. Then notice where He goes and what He does when He gets there. He goes up on the mountain, and He sits down, and He does not begin until His disciples have come to Him. That detail matters more than it looks. This teaching is not shouted at the world at large as the terms of admission to God’s kingdom. It is given to those who have already come, with the crowds listening in over their shoulders, and by the end of chapter seven the crowds will be astonished at His authority. So do not read what follows as a ladder set against heaven’s wall for you to climb. Read it as the description of a life that the King Himself creates in the people He has drawn to Himself, and read it knowing that He is describing the family He is gathering. And sit for a moment with the simple, staggering fact of the scene. The Word who was with God and was God, through whom everything that exists was made, is sitting on a hillside in a backwater province, teaching fishermen. Whatever else you take from this chapter, do not lose that.

Matthew 5:3–5 (BSB)

³ “Blessed are the poor in spirit, for theirs is the kingdom of heaven. ⁴ Blessed are those who mourn, for they will be comforted. ⁵ Blessed are the meek, for they will inherit the earth.

He begins where no one would have begun. Not with the strong, not with the devout, not with the clever, but with the blessed (μακάριος) makarios, pronounced mah-KAR-ee-os. Strong's G3107, blessed, deeply and lastingly flourishing. In older Greek this word belonged to the gods. The makarioi were the blessed ones, the immortals, living above the reach of the accidents and griefs that batter human beings, and by extension the word was used of the wealthy, who could buy their way past most troubles, and of the dead, who were beyond them altogether. Then the translators of the Hebrew Scriptures picked it up and did something wonderful with it. In the Psalms it becomes the word for the man whose delight is in the law of the LORD, for the one whose sin is covered, for the one who takes refuge in Him. It stopped describing a charmed life and started describing a life anchored in God. So when Jesus says makarios nine times running from that hillside, He is not saying “cheerful” and He is not describing a mood at all. He is handing down a verdict from heaven about who is genuinely well off, and the verdict falls on people the world files under unfortunate. This is not sentiment. It is the King telling you the truth about the real state of accounts, and the reason clauses that follow each one show you why: theirs is the kingdom, they will be comforted, they will be filled. Present possession and future certainty, both guaranteed by Him. If He says a mourner is blessed, then the mourner is blessed, whatever the morning feels like. poor in spirit. The phrase means exactly what it sounds like and no more: spiritually destitute, with nothing in hand, nothing in the account, nothing to bring. The word underneath “poor” in the Greek is not the word for a working man with little; it is the word for a beggar, the one crouched at the gate with his hand out, entirely dependent on what someone else gives. And to that person, and to that person first, the King says the kingdom of heaven belongs. Not will belong. Belongs, right now, present tense, “theirs is the kingdom of heaven.” Understand what has just happened. The door into everything Jesus is about to describe is not a qualification but the honest admission that you have none. That is why this beatitude stands first. Everything else in the Sermon rests on it, and every honest reader will be driven back to it before the Sermon is over.

Then the mourners. He does not say blessed are those who feel sad; He says blessed are those who mourn, and in a book where the poverty is poverty of spirit, the mourning is not less than grief over loss but it is certainly more. It is the grief of people who have seen what sin is and what it has done, in the world and in themselves, and who have stopped making excuses for it. And to them He promises comfort, which is the promise the prophets had been carrying for centuries:

"The Spirit of the Lord GOD is on Me, because the LORD has anointed Me to preach good news to the poor. He has sent Me to bind up the brokenhearted, to proclaim liberty to the captives and freedom to the prisoners, to proclaim the year of the LORD’s favor and the day of our God’s vengeance, to comfort all who mourn," Isaiah 61:1–2 (BSB)

Good news to the poor, comfort to all who mourn. The One who reads that scroll aloud in a synagogue and says it is fulfilled in their hearing is the same One sitting on this hillside pronouncing these blessings, and the first two beatitudes are that prophecy taking flesh. Then the third: the meek (πραΰς) praus, pronounced PRAH-oos. Strong's G4239, meek, gentle strength held under control. Praus is one of the most misunderstood words in the New Testament, because our nearest English words have all gone soft. It does not mean timid, spineless, or easily pushed around. In ordinary Greek the word and its family described a gentle breeze rather than a gale, a soothing medicine rather than a harsh one, and an animal that had been brought under the bridle: not an animal with no strength, but an animal whose strength now answers to another’s hand. That is the picture. Meekness is power under authority, and the authority is God’s. It is why Moses, who faced down Pharaoh and shattered a golden calf, could be called the meekest man on the face of the earth, and it is why the Lord Jesus uses this very word of Himself when He says He is gentle and humble in heart, and why Matthew will use it again when the King rides into His own city on a donkey. Here is a man who could have called legions of angels and did not. So the promise is not that doormats inherit the earth. It is that the future belongs to those who have stopped clawing for it and have put their strength into the hands of God, because the earth is His to give, and He has already decided whom He is giving it to. will inherit the earth. Of all the things a first-century Galilean under Roman boots might have expected his Messiah to say about who ends up owning the world, this was not it. And notice He is quoting. The psalmist had said it long before, in a psalm about not fretting when the wicked prosper, and Jesus takes it up and widens it from a strip of land to the whole earth.

"But the meek will inherit the land and delight in abundant prosperity." Psalm 37:11 (BSB)

Matthew 5:6–9 (BSB)

⁶ Blessed are those who hunger and thirst for righteousness, for they will be filled. ⁷ Blessed are the merciful, for they will be shown mercy. ⁸ Blessed are the pure in heart, for they will see God. ⁹ Blessed are the peacemakers, for they will be called sons of God.

Four more, and they turn from what the blessed lack to what the blessed long for and become. Hunger and thirst are not polite words. Jesus is speaking to people who knew what a lean year did to a village, and He picks the two appetites that will not be reasoned with. A man may lose interest in a hundred things, but not in bread and water. Blessed, He says, are those who want righteousness like that, who are not content with their own record and cannot be talked into being content with it. And the promise is not that they will be given a technique. They will be filled. The word He uses is the homely one for a full stomach after a real meal, and He aims it at the soul. Then the merciful, who will be shown mercy, which is not a transaction where we purchase God’s kindness with ours, but the plain observation that a heart which has actually received mercy from God begins to leak it, and a heart with no mercy in it has some explaining to do about what it thinks it received. Then the pure in heart, and hear the word heart, not hands. The Psalms had already tied the two together and set the bar where no one could pretend:

"Who may ascend the hill of the LORD? Who may stand in His holy place? He who has clean hands and a pure heart, who does not lift up his soul to an idol or swear deceitfully." Psalm 24:3–4 (BSB)

Clean hands can be arranged. A pure heart cannot, not by us, and the promise attached to it is the greatest promise in the list: they will see God. Not know about Him. See Him. And then the peacemakers, who are called sons of God, because making peace is the family business. Note the word carefully: not peace-lovers, and not peace-keepers who smooth things over and leave the wound underneath. Peace-makers, who go and do the costly work of putting things right between people, the way their Father went to enormous cost to put things right between Himself and us. A child who does what the Father does gets the family name, and everyone can see the resemblance.

Matthew 5:10–12 (BSB)

¹⁰ Blessed are those who are persecuted because of righteousness, for theirs is the kingdom of heaven. ¹¹ Blessed are you when people insult you, persecute you, and falsely say all kinds of evil against you because of Me. ¹² Rejoice and be glad, because great is your reward in heaven, for in the same way they persecuted the prophets before you.

The list has been running in the third person all the way down, blessed are those, and then without warning it swings around and looks the hearers in the face: “Blessed are you.” That shift is deliberate and it is the moment the Sermon stops being a portrait on the wall and becomes a word spoken to the people sitting in front of Him. And notice what He assumes. He does not say if people insult you. He says when. A life shaped by the eight things He has just described will not be universally admired. It will irritate the world at exactly the points where it is most like Christ, and Jesus adds the qualification that keeps this from becoming an excuse for obnoxiousness: persecuted “because of righteousness,” slandered “because of Me.” Not because we were rude, not because we were tactless, not because we picked a fight. Because of Him. Then comes the command, and it is a startling one to give people who are being lied about: rejoice and be glad. Not endure. Not grit your teeth. The reason is twofold, and both halves lift the eyes off the present. First, “great is your reward in heaven,” which means the accounting is not finished and the One keeping the books is not asleep. Second, “in the same way they persecuted the prophets before you,” which quietly places a slandered believer in the finest company the Old Testament has: Jeremiah in the cistern, Elijah on the run, Micaiah in prison on bread and water. That is the line you have been put in. The blessing is pronounced over exactly the people the world has written off, and it is pronounced by the King Himself. Let that settle. The world’s verdict on a faithful life is not the verdict that will be read out.

Matthew 5:13–16 (BSB)

¹³ You are the salt of the earth. But if the salt loses its savor, how can it be made salty again? It is no longer good for anything, except to be thrown out and trampled by men. ¹⁴ You are the light of the world. A city on a hill cannot be hidden. ¹⁵ Neither do people light a lamp and put it under a basket. Instead, they set it on a stand, and it gives light to everyone in the house. ¹⁶ In the same way, let your light shine before men, that they may see your good deeds and glorify your Father in heaven.

Before a single command arrives, hear the statement of fact. “You are the salt of the earth.” “You are the light of the world.” He does not say become, or try to be, or you will be if you work at it. He tells the people He has just blessed what He has already made them. The doing comes after the being, always, and never the other way around. Then look at the two pictures, because they say different things. Salt in that world was a preservative before it was a seasoning, rubbed into fish and meat to hold back the rot in a country with no ice. Salt works quietly, buried in the thing it is saving, and nobody at the table applauds it. That is one half of a Christian’s presence in the world: hidden, unglamorous, and holding back decay. And His warning about salt losing its savor is not a chemistry lesson but a plain fact of that economy, where salt scraped from the shores of the Dead Sea came mixed with other minerals and could genuinely go flat, at which point it was tipped out onto the path and walked on. A believer whose distinctiveness has dissolved into the surrounding culture has not become a different kind of believer. He has become useless for the one thing he was for.

Light is the other half, and light is the opposite of hidden. “A city on a hill cannot be hidden,” and anyone in Galilee who had walked home at dusk knew the sight of a town’s lamps standing out against a dark hillside for miles. Nobody lights a lamp to shove it under a basket. In a one-room Galilean house a single lamp on its stand was the difference between fumbling and seeing, and it served everyone in the house without being asked. So a life shaped by the Beatitudes will be visible, and it is meant to be, which raises the obvious danger at once. Are we then to perform? He answers before the question can form. “Let your light shine before men, that they may see your good deeds and glorify your Father in heaven.” There is the whole of it. The deeds are to be seen. The glory is to go somewhere else. Two chapters from now He will warn sharply against practicing righteousness to be noticed by men, and there is no contradiction between the two, only a searching question about where the arrow of your visible obedience is pointed. Shine so that they look up, not so that they look at you.

Matthew 5:17–20 (BSB)

¹⁷ Do not think that I have come to abolish the Law or the Prophets. I have not come to abolish them, but to fulfill them. ¹⁸ For I tell you truly, until heaven and earth pass away, not a single jot, not a stroke of a pen, will disappear from the Law until everything is accomplished. ¹⁹ So then, whoever breaks one of the least of these commandments and teaches others to do likewise will be called least in the kingdom of heaven; but whoever practices and teaches them will be called great in the kingdom of heaven. ²⁰ For I tell you that unless your righteousness exceeds that of the scribes and Pharisees, you will never enter the kingdom of heaven.

Here is the hinge of the chapter, and if you lose it you will misread everything that follows. Somebody was evidently already saying that this Galilean was loose with the Law, and He heads it off: “Do not think that I have come to abolish the Law or the Prophets.” Those two words together were how a Jew said the whole of Scripture. And He does not merely deny the charge, He states the positive: He came to fulfill (πληρόω) plēroō, pronounced play-ROH-oh. Strong's G4137, to fill completely, fulfill. Plēroō is an ordinary word for filling something up. You fill a net with fish, a house with fragrance, a valley with earth, a sail with wind. From there it stretches naturally to completing a thing, bringing it all the way to its intended fullness rather than leaving it at half measure. Matthew loves this word. Over and over in his Gospel he stops the narrative to say that something happened “to fulfill what was spoken through the prophet,” and by now his reader has been trained to hear the term as the sound of a long-laid promise arriving. So hear it here. Jesus does not say He came to keep the Law, true as that is, and He certainly does not say He came to replace it. He says He came to fill it full. The Law and the Prophets were never a closed system of regulations; they were a shape, a set of shadows cast backward by something still coming, and He is the substance that fits them. He fulfills the commandments by obeying them perfectly and by opening up their true depth, which is what He is about to do six times over. He fulfills the sacrifices by being one. He fulfills the prophets by being what they saw. Nothing is discarded. Everything arrives. And that is why the paragraphs that follow are not corrections of Moses but the Author of the Law telling you at last what He always meant. them. Then He puts it as strongly as language allows. Not a single jot, which is the yod, the smallest letter in the Hebrew alphabet, hardly more than a mark; not a stroke of a pen, the tiny serif that distinguishes one Hebrew letter from another. Heaven and earth will go before any of it does. God’s Word is not provisional. And then verse twenty, which must have landed on that hillside like a stone in still water: “unless your righteousness exceeds that of the scribes and Pharisees, you will never enter the kingdom of heaven.” Understand what that meant to them. The Pharisees were the men who tithed their garden herbs and fasted twice a week and counted the steps they took on the Sabbath. If those men had not done enough, who possibly could? But look closely and you will see He does not say more righteousness. He says righteousness that exceeds, that goes beyond, and the six paragraphs that follow will show exactly what direction “beyond” runs. Not further out into more rules. Further in, to the heart, where no amount of external compliance reaches, and where only God can work.

Matthew 5:21–26 (BSB)

²¹ You have heard that it was said to the ancients, ‘Do not murder’ and ‘Anyone who murders will be subject to judgment.’ ²² But I tell you that anyone who is angry with his brother will be subject to judgment. Again, anyone who says to his brother, ‘Raca,’ will be subject to the Sanhedrin. But anyone who says, ‘You fool!’ will be subject to the fire of hell. ²³ So if you are offering your gift at the altar and there remember that your brother has something against you, ²⁴ leave your gift there before the altar. First go and be reconciled to your brother; then come and offer your gift. ²⁵ Reconcile quickly with your adversary, while you are still on the way to court. Otherwise, he may hand you over to the judge, and the judge may hand you over to the officer, and you may be thrown into prison. ²⁶ Truly I tell you, you will not get out until you have paid the last penny.

Now the pattern begins, and it will run six times: “You have heard that it was said… But I tell you.” Watch the wording, because it is exact. He does not say “it is written,” which is how He speaks of Scripture. He says “you have heard that it was said,” which is how a man speaks of what has been taught and handed down and applied. He is not standing over Moses with a red pen. He is taking a command that had been reduced to a line you must not cross and showing what it was always guarding. Do not murder, said the sixth commandment, and everyone in the crowd could say honestly that they had kept it. Then He opens the floor of it. Anyone who is angry with his brother is already in the dock. Anyone who says Raca, an Aramaic term of contempt, something close to “empty head,” answers to the council. Anyone who says “You fool!” is in danger of the fire of hell. He is climbing a ladder of ordinary contempt and telling us that every rung of it is on the same continuum as the killing we all agree is monstrous. Murder is the fruit; this is the root. John, who was sitting somewhere on that hillside, never forgot it:

"Everyone who hates his brother is a murderer, and you know that eternal life does not reside in a murderer." 1 John 3:15 (BSB)

And then, having exposed the heart, He does not leave us to brood about it. He sends us to the door. Picture the scene He paints: a man has traveled up to Jerusalem, waited his turn in the temple courts, and is standing there with his offering in his hands when it comes back to him that his brother has something against him. Leave the gift, He says. Leave it lying there in front of the altar and go. There is no more vivid way to say that God will not be worshiped by a man who is content to be at war with his neighbor, and notice that the offense in view is not even one you are nursing but one held against you. Go anyway. Go first. Then He shifts the picture to a debtor being marched toward court, and the counsel is the same, only now with urgency behind it: settle it while there is still road left, because once the process has run its course the terms are no longer yours to set. Reconciliation delayed hardens. Deal with it today.

Matthew 5:27–30 (BSB)

²⁷ You have heard that it was said, ‘Do not commit adultery.’ ²⁸ But I tell you that anyone who looks at a woman to lust after her has already committed adultery with her in his heart. ²⁹ If your right eye causes you to sin, gouge it out and throw it away. It is better for you to lose one part of your body than for your whole body to be thrown into hell. ³⁰ And if your right hand causes you to sin, cut it off and throw it away. It is better for you to lose one part of your body than for your whole body to depart into hell.

The same method, applied to the seventh commandment. Adultery was a public act with witnesses and consequences, and a man could keep clear of it while his inner life ran wherever it pleased. Jesus closes that gap. The line He draws is not at the act; it is at the look that intends the act, “anyone who looks at a woman to lust after her.” Be careful to hear what He does and does not say. He is not condemning the eye that notices that another person is beautiful, which is simply the eye working. The verb reaches past noticing to wanting, to the settled turning of a person made in God’s image into an object to be consumed in the imagination. And He says such a look is not a lesser thing than adultery in kind but the same thing at an earlier stage, “already committed adultery with her in his heart.” The example is put in the terms of that room, spoken to a crowd where men would have been the ones nodding along at how well they had kept the seventh commandment, but the principle He is exposing is not the property of one sex or one kind of person. Every human heart has an inner life that no one audits, and every one of us has learned to keep the outside respectable. That is the whole point of the Sermon. God has always been reading the heart, and the commandment was never merely about the bed.

And then the language turns violent, and it is meant to. If your right eye causes you to sin, tear it out. If your right hand causes you to sin, cut it off. Say plainly what this is: it is deliberate hyperbole, an intentional overstatement, and Jesus uses it elsewhere in the same way when He speaks of a camel through a needle’s eye or a plank in your own eye. We know it is not a literal command because it would not even work. A blind man can still lust; the trouble was never in the eye. But do not use that to defuse it, because hyperbole is not decoration. It is the strongest way a teacher has of saying the stakes here are exactly as serious as this sounds. He names the right eye and the right hand, which in that culture meant the best and most valued of a pair, and He says that if the choice really came down to losing the thing you prize most or losing everything, the arithmetic is not close. He is talking about hell, twice, in two verses, soberly and without a trace of relish. So the call is not to mutilation. It is to a decisiveness about sin that most of us have never seriously considered: cut off the access, break the habit, end the arrangement, whatever it costs and however much it feels like losing a limb. A person who has genuinely reckoned with what Jesus says here will do something concrete, and will do it today rather than negotiating.

Matthew 5:31–32 (BSB)

³¹ It has also been said, ‘Whoever divorces his wife must give her a certificate of divorce.’ ³² But I tell you that anyone who divorces his wife, except for sexual immorality, brings adultery upon her. And he who marries a divorced woman commits adultery.

He is quoting a provision from Deuteronomy, and it helps enormously to see the original in its own setting:

"If a man marries a woman, but she becomes displeasing to him because he finds some indecency in her, he may write her a certificate of divorce, hand it to her, and send her away from his house." Deuteronomy 24:1 (BSB)

That law was not written to make divorce easy. It was written into a world where a man could simply put a woman out of the house, and it required a legal document, which protected her: it proved she was not a runaway wife and left her free to remarry rather than destitute and suspect. But the phrase “some indecency” was ambiguous, and by Jesus’ day two whole schools had grown up around it. The stricter reading, associated with Shammai, confined it to serious sexual sin. The looser reading, associated with Hillel, stretched it until a man could dismiss his wife for almost any displeasure. The crowd would have known that argument the way we know the arguments of our own day, and here is Jesus, refusing to referee the dispute on its own terms and going instead to what marriage actually is. Later, when the Pharisees press Him on this same question, He will take them back past Moses to the garden, to the two becoming one flesh, and say that what God has joined together man must not separate, and that the Mosaic provision was a concession to hardness of heart and not the way it was from the beginning. That is the foundation under these two verses. Marriage is the covenant union of one man and one woman, made by God and not merely arranged by the parties, and it is meant to last as long as they do. Through Malachi the LORD declared His hatred of divorce, said that a man who dismisses his wife covers his garment with violence, and told His people to guard themselves in their spirit and not break faith. God takes the wound of a broken marriage with total seriousness, and so should we.

Now, the exception, and here honesty is required of anyone who teaches this. Jesus says “except for sexual immorality,” rendering a Greek word, porneia, that covers sexual sin broadly. Faithful believers who hold Scripture to be the very Word of God have read the scope of that clause in more than one way. Many take it plainly to mean that sexual unfaithfulness breaks the covenant and that the innocent party is not held guilty in a divorce on that ground; among those, some hold that remarriage is then permitted and others hold that it is not. Some understand porneia more narrowly, of unlawful unions or of unfaithfulness discovered during the Jewish betrothal period, which is what Joseph faced with Mary in chapter one. Paul later addresses a further situation, desertion by an unbelieving spouse, which the Sermon does not take up. These are genuine differences among people who love the Lord and tremble at His Word, and it would not be honest to hand you a settled verdict this text does not give. What must not be lost in the disagreement is the thing Jesus plainly says, which is that marriage is not disposable and that a man who dismisses his wife because he has tired of her has done real and lasting damage. Notice, too, whom the Lord is protecting here. In a world where the power to end the marriage sat almost entirely on one side, He speaks up for the one being sent away. And hear this before you leave the paragraph: every reader comes to it with a different history, and some come to it out of grief they did not choose. This is not a stone to be picked up and thrown, and the Sermon that says it opened by pronouncing blessing on the poor in spirit and the mourners, and has room for both. Whatever lies behind any of us, the door into this kingdom is still the empty hands of verse three.

Matthew 5:33–37 (BSB)

³³ Again, you have heard that it was said to the ancients, ‘Do not break your oath, but fulfill your vows to the Lord.’ ³⁴ But I tell you not to swear at all: either by heaven, for it is God’s throne; ³⁵ or by the earth, for it is His footstool; or by Jerusalem, for it is the city of the great King. ³⁶ Nor should you swear by your head, for you cannot make a single hair white or black. ³⁷ Simply let your ‘Yes’ be ‘Yes,’ and your ‘No,’ ‘No.’ Anything more comes from the evil one.

This one takes a little cultural distance to feel. The Law required that a vow made to the LORD be kept, and out of that had grown a whole graded system of oath-taking. Swear by the temple and it did not bind you; swear by the gold of the temple and it did. Swear by heaven, by the earth, by Jerusalem, by your own head, each with its own weight, and the effect was a highly developed technology for sounding sincere while keeping an exit. Jesus demolishes the entire apparatus with one observation. You cannot swear by anything that is not God’s. Heaven is His throne, earth is His footstool, Jerusalem is the city of the great King, and even your own head is so little yours that you cannot turn one hair of it white or black by wishing. Every oath drags God in, whether His name is spoken or not, which means the whole game of calibrated credibility was a fiction from the start. Then the alternative, and it is beautifully simple: let your yes be yes and your no be no. Say the thing and then do the thing. A person whose plain word can be relied on has no need of a ladder of oaths, and the elaborate machinery of swearing exists chiefly because ordinary speech has become untrustworthy. Some believers have read verse thirty-four as forbidding even a courtroom oath, and they hold that conscientiously; others note that Paul calls God as his witness and that God Himself swore by His own name, and conclude that the target is the everyday inflation of our speech. Either way the aim of the passage is not in doubt. In the kingdom, truthfulness is not something you switch on for solemn occasions. It is the ordinary condition of your mouth.

Matthew 5:38–42 (BSB)

³⁸ You have heard that it was said, ‘Eye for eye and tooth for tooth.’ ³⁹ But I tell you not to resist an evil person. If someone slaps you on your right cheek, turn to him the other also; ⁴⁰ if someone wants to sue you and take your tunic, let him have your cloak as well; ⁴¹ and if someone forces you to go one mile, go with him two miles. ⁴² Give to the one who asks you, and do not turn away from the one who wants to borrow from you.

“Eye for eye and tooth for tooth” sounds savage to modern ears, and it was in fact one of the great mercies of the Law. It was given to judges, not to victims, and its whole force was as a limit: the penalty may match the injury and may not exceed it. No family feuds, no escalating vengeance, no life taken for a tooth. But a rule given to restrain the courts had been quietly borrowed as a charter for personal payback, and it is that borrowing Jesus overturns. He gives three pictures, all of them small and specific. A slap on the right cheek, delivered by a right-handed man, is a backhanded blow, which in that world was less an assault than an insult, the way you struck an inferior. A lawsuit over a man’s tunic, his inner garment, and the cloak thrown in as well, though the Law itself forbade keeping a poor man’s cloak overnight because he slept in it. And the mile, which every Galilean felt in his bones: a Roman soldier could legally compel a civilian to carry his load for one mile, and Jesus says go two. Each picture is the same move. Absorb the insult rather than return it. Give more than is demanded rather than fight for the last inch. Refuse to let another man’s evil set the terms of your response.

Now be careful, because this passage has been made to say things it does not say. Jesus is not abolishing courts, or civil justice, or the protection of the weak; He has just insisted that not a stroke of the Law will pass away, and Scripture elsewhere gives the magistrate a sword for precisely this purpose. Nor is He telling anyone to stand still under ongoing violence, and it is a cruelty to use these verses that way. What He is dismantling is the instinct for personal retaliation, the reflex that must get even, the bookkeeping of grudges. And verse forty-two widens it from what you will not take back to what you will freely give: give to the one who asks, do not turn away the one who wants to borrow. Open-handed, not calculating. It is the behavior of people who know that their real treasure is not in this account and cannot be taken from them, and who have therefore stopped defending a life they have already handed over to God.

Matthew 5:43–47 (BSB)

⁴³ You have heard that it was said, ‘Love your neighbor’ and ‘Hate your enemy.’ ⁴⁴ But I tell you, love your enemies and pray for those who persecute you, ⁴⁵ that you may be sons of your Father in heaven. He causes His sun to rise on the evil and the good, and sends rain on the righteous and the unrighteous. ⁴⁶ If you love those who love you, what reward will you get? Do not even tax collectors do the same? ⁴⁷ And if you greet only your brothers, what are you doing more than others? Do not even Gentiles do the same?

Notice the quotation this time, because half of it is not in the Bible at all. “Love your neighbor” is straight from Leviticus:

"Do not seek revenge or bear a grudge against any of your people, but love your neighbor as yourself. I am the LORD." Leviticus 19:18 (BSB)

“Hate your enemy” is nowhere in the Law of God. It is the addition, the inference people had drawn and then repeated until it sounded like Scripture, and it is worth pausing over how easily that happens in any age. Command the love of neighbor and the human heart will immediately set about drawing the boundary of the word neighbor, and everyone outside the line is fair game. Jesus erases the line. “Love your enemies and pray for those who persecute you.” He does not say approve of them, or pretend the enmity is not real, or call evil good. He says love them, and then He gives the one action that makes such love more than a sentiment: pray for them. It is very hard to go on hating a person you are genuinely bringing before God.

And then the reason, which is the deepest thing in the chapter. Do it “that you may be sons of your Father in heaven,” and here is what your Father is like: “He causes His sun to rise on the evil and the good, and sends rain on the righteous and the unrighteous.” Go and stand in a field at sunrise and think about that. Every morning God warms the faces of people who curse Him. Every spring He waters the fields of men who will never thank Him for a single harvest. The rain that fell last night fell on the just and the unjust alike, and it fell because He sent it. That is not indifference; it is a lavish, patient, undiscriminating kindness that has been pouring out over this rebel world since Eden, and it is the reason any of us drew breath long enough to repent. Children resemble their Father, and this is the family likeness the King is after. Then the closing questions, and they are gentle but they do not let go. If you love the people who love you back, what have you actually done? The tax collectors, the most despised men in the province, manage that much. If you greet only your own, what are you doing more than anyone else? Ordinary decency is not the standard. The standard is the character of God.

Matthew 5:48 (BSB)

⁴⁸ Be perfect, therefore, as your heavenly Father is perfect.

And there it stands, one sentence, and it has ended many a reading of this chapter in despair. Take it slowly, and take the word “therefore” first, because it ties this verse to the paragraph just finished and not to the whole of human moral striving in the abstract. The Father has just been described sending sun and rain on the evil and the good. Then: be perfect (τέλειος) teleios, pronounced TEL-ay-oss. Strong's G5046, complete, mature, fully grown. Teleios comes from telos, the end or goal of a thing, and it means having arrived at what it was made for. It is used of a grown adult as distinct from a child, of a mature believer as distinct from one still on milk, of a work of endurance allowed to finish so that nothing is lacking. So the word is not primarily about a flawless record; it is about wholeness, completeness, the undivided thing. Behind it stands the Hebrew tamim, which the Law used for a sacrifice without blemish and which God used when He told Israel through Moses, “You must be blameless before the LORD your God.” Whole-hearted. Nothing held back, no sector of life quietly exempted. That is the summons, and it is not a lower bar than the English word “perfect” suggests, because the standard given is nothing less than the Father Himself. Which is exactly why this verse is where the Sermon has been driving all along. Any reader honest enough to have felt the weight of anger and the look and the grudge and the enemy will get here and know that he cannot produce this. Good. That knowledge is not the failure of the Sermon; it is its success, and the road it opens runs straight back to the first thing the King said on that mountain: blessed are the poor in spirit, for theirs is the kingdom of heaven. You come with empty hands, and He gives you the kingdom, and then He begins to make you like Himself. , therefore, as He is. Luke records the same summons in the words “Be merciful, just as your Father is merciful.” The perfection in view is first of all a love that is not truncated, that does not stop at the boundary of those who deserve it, because His does not. That is what is being held out.
