Romans 9 — I Will Have Mercy on Whom I Have Mercy

Today’s Passage: Romans 9

After eight chapters that climb to the great assurance that nothing can separate us, Paul turns and weeps. If the gospel is that sure, why has so much of Israel not received it? Has the word of God failed? Romans 9 is his answer, and it is a hard chapter, one we must not break into three separate sermons. Election, the remnant, and the calling of the Gentiles are not three lessons but one argument: God’s word has not failed, because mercy belongs to the God who is free to give it. He has always advanced His purpose by promise and call, not by bloodline or by works. When He says, “I will have mercy on whom I have mercy,” we must not soften the sentence to make it gentler than it is. The chapter is written by a man in tears, and it is written by a man who will not empty God’s freedom.

As you read, hold this: Mercy belongs to the God who is free to give it.

Romans 9:1–5 (BSB)

¹ I speak the truth in Christ; I am not lying, as confirmed by my conscience in the Holy Spirit. ² I have deep sorrow and unceasing anguish in my heart. ³ For I could wish that I myself were cursed and cut off from Christ for the sake of my brothers, my own flesh and blood, ⁴ the people of Israel. Theirs is the adoption as sons; theirs the divine glory and the covenants; theirs the giving of the law, the temple worship, and the promises. ⁵ Theirs are the patriarchs, and from them proceeds the human descent of Christ, who is God over all, forever worthy of praise! Amen.

Before a single word of doctrine, there are tears. The apostle who has just sung that nothing can separate us from God’s love now carries unceasing anguish, and the cause of it is the unbelief of his own people. So far is he from the cold calculation that people sometimes imagine in this chapter that he could almost wish himself cursed and cut off from Christ for their sake, an echo of Moses, who offered to be blotted out of God’s book for Israel (Exodus 32:32). Whatever Romans 9 teaches about God’s freedom, it is written by a man weeping. Then comes the catalogue of Israel’s privileges, climaxing in one of the clearest confessions of Christ’s deity in all of Paul: Christ “who is God over all, forever worthy of praise.” The grief is real because the privilege was real.

Romans 9:6–9 (BSB)

⁶ It is not as though God’s word has failed. For not all who are descended from Israel are Israel. ⁷ Nor because they are Abraham’s descendants are they all his children. On the contrary, “Through Isaac your offspring will be reckoned.” ⁸ So it is not the children of the flesh who are God’s children, but it is the children of the promise who are regarded as offspring. ⁹ For this is what the promise stated: “At the appointed time I will return, and Sarah will have a son.”

Here is the thesis, stated as a flat denial of the feared conclusion: “It is not as though God’s word has failed.” The word never guaranteed what was assumed of it. “Not all who are descended from Israel are Israel,” Paul says, for within the physical nation there has always been a true Israel marked by promise and not by pedigree. Abraham had other sons, but the line ran through Isaac. The decisive category is the children of the promise, those reckoned as offspring by God’s word and not by descent alone. God’s saving purpose has always advanced by promise and call, so that the narrowness now is not a new failure but an old and familiar pattern. Mercy has always been God’s to give.

Romans 9:10–13 (BSB)

¹⁰ Not only that, but Rebecca’s children were conceived by one man, our father Isaac. ¹¹ Yet before the twins were born or had done anything good or bad, in order that God’s plan of election might stand, ¹² not by works but by Him who calls, she was told, “The older will serve the younger.” ¹³ So it is written: “Jacob I loved, but Esau I hated.”

Paul presses harder with a case no one could explain away by merit. Jacob and Esau shared one father, one mother, and one womb, and yet before either of them had done anything, the word came: “The older will serve the younger.” The timing is the argument. The choice rested “not by works but by Him who calls,” so that God’s plan of eklogē (ἐκλογή) eklogē, pronounced ek-lo-GAY. Strong's G1589, a choosing out, selection, election. Eklogē is built from ek (“out of”) and legō (“to gather, to pick”), and it means a selecting out, a choice. Paul uses it of God’s “plan of election” (literally, that the purpose of God according to election might stand), and the whole point is when the choice was made: before the twins were born or had done anything good or bad. The word locates the ground of God’s choosing not in the merit of the chosen but in the freedom of the Chooser. Later Paul will use the same root to comfort rather than to crush, for there remains “a remnant chosen by grace” (Romans 11:5). Eklogē makes clear that salvation begins on God’s side, and that is why mercy belongs to the God who is free to give it. would stand upon God’s freedom and not upon human achievement. “Jacob I loved, but Esau I hated” is the most jarring line in the chapter; in Malachi it speaks of two nations, and the idiom is comparative. However far one presses it, and faithful readers press it differently, Paul’s point is unmistakable: God’s saving choice begins on God’s side, before we have done anything to earn it or to forfeit it. That is humbling, and for the anxious it is also, strangely, freeing.

Romans 9:14–18 (BSB)

¹⁴ What then shall we say? Is God unjust? Certainly not! ¹⁵ For He says to Moses: “I will have mercy on whom I have mercy, and I will have compassion on whom I have compassion.” ¹⁶ So then, it does not depend on man’s desire or effort, but on God’s mercy. ¹⁷ For the Scripture says to Pharaoh: “I raised you up for this very purpose, that I might display My power in you, and that My name might be proclaimed in all the earth.” ¹⁸ Therefore God has mercy on whom He wants to have mercy, and He hardens whom He wants to harden.

Paul knows the objection (“Is God unjust?”) and answers it not with a theory but with a verdict and a verse. “Certainly not!” The proof is God’s own self-revelation to Moses, and it stands at the very heart of the chapter. Mercy cannot be earned by desire or by effort, for then it would no longer be mercy but wages. Paul’s defense of God’s justice is to insist that no one is owed salvation, and therefore God commits no injustice when He shows mercy freely. The original setting makes this sweeter rather than softer, for these words came in Exodus 33 as God promised to show goodness to a people fresh from the golden calf.

We must not empty verses 15 through 18 to make them gentler, for the counterpart is as hard as the mercy is free. God raised Pharaoh up, and He hardens whom He wants to harden. Yet the Exodus account holds both truths together: God hardened Pharaoh’s heart, and Pharaoh hardened his own. What Paul affirms is that even Pharaoh’s defiance did not thwart God but served Him, so that the name of God was proclaimed in all the earth through the very resistance that was meant to oppose Him. The freedom is total, and the responsibility is not erased; we are meant to hold both and to flatten neither. Mercy belongs to the God who is free, free to give it, and free not to be managed by the clay.

Romans 9:19–24 (BSB)

¹⁹ One of you will say to me, “Then why does God still find fault? For who can resist His will?” ²⁰ But who are you, O man, to talk back to God? Shall what is formed say to Him who formed it, “Why did You make me like this?” ²¹ Does not the potter have the right to make from the same lump of clay one vessel for special occasions and another for common use? ²² What if God, intending to show His wrath and make His power known, bore with great patience the vessels of His wrath, prepared for destruction? ²³ What if He did this to make the riches of His glory known to the vessels of His mercy, whom He prepared in advance for glory— ²⁴ including us, whom He has called not only from the Jews, but also from the Gentiles?

Paul lets the objection speak out loud, and his first answer is not an explanation but a reorientation: “who are you, O man, to talk back to God?” This is not God evading the question; it is God setting the questioner back in his proper place. The creature is not the Creator’s peer in a courtroom. A vessel does not shape itself, and it has no standing to arraign the potter. What Paul dismantles is the posture of the clay that would presume to instruct the hand that formed it.

Then the metaphor turns toward grace. Toward the vessels of wrath God “bore with great patience,” a word for forbearance, the holding back of deserved judgment. The vessels are “prepared for destruction,” yet Paul does not say that God prepared them so; the grammar leaves room, and many faithful readers hear here a ripeness for ruin that is self-incurred. Toward the vessels of His mercy, however, the language is unmistakably active: God prepared them in advance for glory. That asymmetry is the point. And then the view opens wide: “us, whom He has called not only from the Jews, but also from the Gentiles.” The whole hard argument has been bending toward this open door all along, and the God who is free to have mercy has swung it wide to the nations.

Romans 9:25–29 (BSB)

²⁵ As He says in Hosea: “I will call them ‘My People’ who are not My people, and I will call her ‘My Beloved’ who is not My beloved,” ²⁶ and, “It will happen that in the very place where it was said to them, ‘You are not My people,’ they will be called ‘sons of the living God.’” ²⁷ Isaiah cries out concerning Israel: “Though the number of the Israelites is like the sand of the sea, only the remnant will be saved. ²⁸ For the Lord will carry out His sentence on the earth thoroughly and decisively.” ²⁹ It is just as Isaiah foretold: “Unless the Lord of Hosts had left us descendants, we would have become like Sodom, we would have resembled Gomorrah.”

Now the prophets are called as witnesses that none of this is improvisation. From Hosea comes the word that God will make a people of “not My people,” the outsiders, the Gentiles, called sons of the living God; from Isaiah comes the word that within Israel only the remnant will be saved. Both quotations serve the same point Paul has been making since verse 6, that God’s people have always been defined by His call and not by sheer numbers or lineage. And there is mercy threaded even through the warning, for unless the Lord of Hosts had left descendants, Israel would have become like Sodom. The remnant exists at all only because God preserved it, so that His sovereignty here is not cold but is the very reason anyone is saved at all.

Romans 9:30–33 (BSB)

³⁰ What then will we say? That the Gentiles, who did not pursue righteousness, have obtained it, a righteousness that is by faith; ³¹ but Israel, who pursued a law of righteousness, has not attained it. ³² Why not? Because their pursuit was not by faith, but as if it were by works. They stumbled over the stumbling stone, ³³ as it is written: “See, I lay in Zion a stone of stumbling and a rock of offense; and the one who believes in Him will never be put to shame.”

Here, at the chapter’s close, is the truth that keeps the whole from collapsing into fatalism: human responsibility is real, and it is named. The Gentiles obtained righteousness, and they obtained it by faith. Israel pursued a law of righteousness and did not attain it. Why not? Paul’s answer is not “because God chose otherwise.” It is “because their pursuit was not by faith, but as if it were by works. They stumbled.” They stumbled over the skandalon (σκάνδαλον) skandalon, pronounced SKAN-dah-lon. Strong's G4625, stumbling block, trap, offense. Skandalon is the trigger of a trap, the very thing that catches the foot and pitches a person forward. The BSB’s “rock of offense” renders this word. Paul is quoting Isaiah 8:14 and 28:16, where God lays a stone in Zion, and the same stone is either a foundation or a skandalon. That stone is Christ, and self-righteousness trips over Him while faith rests upon Him. The word keeps the chapter from collapsing into fatalism, for Israel stumbled, an active verb, a real failure, a refusal of the way of faith. The God who is free to show mercy is dealing with people who genuinely stumble over the stone, and so freedom and responsibility sit together in the same sentence. And the last word is invitation: the one who believes in Him will never be put to shame. , over Christ Himself. The same God who is sovereignly free to show mercy is dealing with people who genuinely refuse the way of faith, and the chapter holds both truths without apology. The last word is pure invitation, for the chapter that began in tears ends with an open door wide enough for anyone who will believe. Mercy is still God’s, God is still free, and the hand that receives it is still empty.
