Day 3 · The Gospel of John: The Word Became Flesh

John 1:19–51

John 1:19–51 — Behold, the Lamb of God

Pray to Begin

Ask — that the Holy Spirit, who pointed the first witnesses to the Lamb of God, would open your eyes today to see the same Jesus they saw, and to hear His invitation as if spoken to you.

Give thanks — that the One who takes away the sin of the world is not hidden behind a delegation of officials or a wall of qualifications, but stands near, calling ordinary people to come and see.

Yield — every assumption about who Jesus must be, every “can anything good come from there?” that has kept you at a distance, and let Him be revealed to you as He truly is.

Today’s Passage: John 1:19–51

The Prologue is finished; the music has sounded its themes. Now the curtain rises and the people enter. The first character to walk onto the stage is the man the Prologue already named — John, the witness who is “not the Light” but came “to testify about the Light” (1:8). These verses cover three consecutive days. On the first, a delegation from Jerusalem interrogates John about his identity, and he answers entirely in negatives, pointing away from himself to One who “stands among you” unrecognized. On the second, John sees Jesus and cries the line that names this whole day: “Look, the Lamb of God, who takes away the sin of the world!” On the third, the witness’s testimony bears its fruit — his own disciples leave him to follow Jesus, and a chain of “come and see” begins that gathers Andrew, Peter, Philip, and Nathanael. The Gospel of John is, from its first chapter, a Gospel of testimony and response: someone points to Jesus, and someone comes. (The full text is quoted block by block in the commentary below.)

As you read, hold this: The witness points away from himself, and the first disciples come and see.

Context The world of John 1:19–51

The delegation from Jerusalem. John’s ministry had grown large enough to demand official attention. The Jewish leadership in Jerusalem — “the Jews,” John’s frequent shorthand for the religious authorities — sent “priests and Levites” (1:19), and behind them stood “the Pharisees” (1:24), to investigate this wilderness preacher drawing crowds. Their questions are not idle: they are checking his credentials against the menu of figures Israel expected before the end. Was he the Christ? Elijah, who Malachi 4:5 said would come before the great day of the LORD? the Prophet, the one like Moses promised in Deuteronomy 18:15? John denies all three titles for himself, claiming only to be “a voice” (Isaiah 40:3) — a sound that exists to announce someone else.

Baptizing at Bethany beyond the Jordan. John specifies the location: “Bethany beyond the Jordan” (1:28) — not the Bethany near Jerusalem, but a site east of the river, on the edge of the wilderness where Israel had once crossed into the Promised Land under Joshua. The geography preaches: at the very threshold where the nation entered its inheritance, a new beginning is being announced, and the people come out to the wilderness to be readied.

The Lamb of God: Passover and Isaiah 53. John’s cry, “Behold, the Lamb of God” (1:29), draws on the deepest wells of Israel’s worship. Twice daily a lamb was offered in the Temple. Once a year, at Passover, every household killed a lamb and painted its blood on the doorframe so the angel of death would pass over (Exodus 12). And the prophet Isaiah had spoken of a Servant who would bear the iniquity of many, “led like a lamb to the slaughter” (Isaiah 53:7). For John to point at a living man and call Him the Lamb — the Lamb of God, provided by God Himself — and to say He “takes away the sin of the world” was to gather every sacrificial thread of the Old Testament into one Person and stretch it beyond Israel to the whole earth.

Rabbinic discipleship and “come and see.” In Jesus’ world, a would-be disciple normally sought out a rabbi and applied to follow him. What is striking in John 1 is how the call moves both ways: two of John’s disciples follow Jesus on their own initiative (1:37), and Jesus turns and welcomes them with “Come and see” (1:39); then Jesus Himself takes the initiative, finding Philip and saying “Follow Me” (1:43). The simple, repeated invitation — “Come and see” (1:39, 46) — becomes the pattern of all evangelism in this Gospel: not argument that compels, but invitation that introduces. Andrew brings Peter; Philip brings Nathanael; each one says, in effect, come and look for yourself.

Jacob’s ladder and the Son of Man. Jesus’ closing words to Nathanael — “you will all see heaven open and the angels of God ascending and descending on the Son of Man” (1:51) — deliberately echo Jacob’s dream at Bethel (Genesis 28:12), where Jacob saw a ladder set up between earth and heaven with the angels of God going up and down on it. There the meeting-place of heaven and earth was a stone and a staircase in a dream. Here Jesus says: I am that place. The true ladder, the true Bethel (“house of God”), the true gate of heaven, is the Son of Man Himself — the title (from Daniel 7:13) Jesus most often takes for Himself.

John 1:19–23 (BSB)

¹⁹ And this was John’s testimony when the Jews of Jerusalem sent priests and Levites to ask him, “Who are you?” ²⁰ He did not refuse to confess, but openly declared, “I am not the Christ.” ²¹ “Then who are you?” they inquired. “Are you Elijah?” He said, “I am not.” “Are you the Prophet?” He answered, “No.” ²² So they said to him, “Who are you? We need an answer for those who sent us. What do you say about yourself?” ²³ John replied in the words of Isaiah the prophet: “I am a voice of one calling in the wilderness, ‘Make straight the way for the Lord.’”

The Prologue called John a witness; now we hear the witness testify. The delegation comes with a single, pressing question — “Who are you?” — and runs through the checklist of Israel’s expected figures. John’s answers grow shorter and starker: a full sentence (“I am not the Christ”), then two words (“I am not”), then a single word (“No”). The deflection is deliberate and beautiful. A lesser man, with crowds streaming to him, might have claimed at least something. John empties himself of every title until only one identity remains, and it is not a person but a sound: “I am a voice.” Borrowing Isaiah 40:3, he makes himself the herald who runs ahead shouting that the King is coming and then falls silent so the King can be heard. A voice exists only for the word it carries. That is the whole vocation of the witness.

John 1:24–28 (BSB)

²⁴ Then the Pharisees who had been sent ²⁵ asked him, “Why then do you baptize, if you are not the Christ, nor Elijah, nor the Prophet?” ²⁶ “I baptize with water,” John replied, “but among you stands One you do not know. ²⁷ He is the One who comes after me, the straps of whose sandals I am not worthy to untie.” ²⁸ All this happened at Bethany beyond the Jordan, where John was baptizing.

If John is none of the great figures, the Pharisees press, what gives him the right to baptize — to summon Israel to the kind of cleansing one might expect only at the dawn of the messianic age? John’s answer does not defend his own authority at all; it pivots immediately to Another. “I baptize with water” — a mere preparation — “but among you stands One you do not know.” The most important Person in the scene is already present, unnoticed, standing in the very crowd that is questioning John. The tragedy of the Prologue (“the world did not recognize Him,” 1:10) is enacted in miniature: He stands among them and they do not know Him. And John measures the distance between himself and this One with a vivid image — to untie a master’s sandal was the task of the lowest household slave, and John counts himself unworthy of even that. The greater the witness, the smaller he makes himself before the One he announces.

John 1:29–34 (BSB)

²⁹ The next day John saw Jesus coming toward him and said, “Look, the Lamb of God, who takes away the sin of the world! ³⁰ This is He of whom I said, ‘A man who comes after me has surpassed me because He was before me.’ ³¹ I myself did not know Him, but the reason I came baptizing with water was that He might be revealed to Israel.” ³² Then John testified, “I saw the Spirit descending from heaven like a dove and resting on Him. ³³ I myself did not know Him, but the One who sent me to baptize with water told me, ‘The man on whom you see the Spirit descend and rest is He who will baptize with the Holy Spirit.’ ³⁴ I have seen and testified that this is the Son of God.”

Word study "Lamb" — amnos (John 1:29, 36)

This passage turns on a handful of Greek words that carry far more than their English renderings can hold. Four of them open the heart of the day.

Greek: ἀμνός (amnos), pronounced am-NOS. Strong’s G286.

Amnos is “lamb” — but not just any young sheep. In the Septuagint it is the word for the sacrificial lamb: the lamb of the daily offering (Exodus 29:38–39), and above all the lamb led silently to slaughter in Isaiah 53:7. The New Testament uses amnos for Jesus only a handful of times, and each is loaded with sacrifice: here in John’s cry, and in Peter’s declaration that we were redeemed “with the precious blood of Christ, a lamb without blemish or spot” (1 Peter 1:19). When John the Baptist says “the Lamb of God,” a first-century Jewish ear would hear at least two melodies at once — the Passover lamb whose blood marked the doors of Israel for deliverance (Exodus 12), and the suffering Servant of Isaiah 53 who is “led like a lamb to the slaughter.” John fuses them into one and adds what no one expected: this Lamb does not merely cover Israel’s sin but “takes away the sin of the world.”

“The next day” — and the unknown One standing in the crowd now steps into view. John points and gives Jesus the title that will echo through the whole Bible to the throne of the Lamb in Revelation: “Look, the Lamb of God” (amnos, am-NOS), “who takes away the sin of the world!” In one sentence John fuses the Passover lamb and Isaiah’s suffering Servant and casts the net wider than any prophet dared — not the sins of Israel only, but “the sin of the world.” Verse 30 reaches back to the Prologue’s paradox: the One who comes after John in time “was before” him in eternity (cf. 1:15). Twice John confesses “I myself did not know Him” (vv. 31, 33) — even the forerunner needed Jesus revealed to him, by the sign God had promised: the Spirit “descending… like a dove and resting on Him.” The Greek for resting is the abiding word again — the Spirit does not merely visit but remains on Jesus, marking Him as the one who will “baptize with the Holy Spirit,” doing inwardly what John’s water could only picture outwardly. The witness ends at his highest note: “this is the Son of God.”

This is the verse to carry from today — the witness’s cry that names the whole day:

John 1:35–39 (BSB)

³⁵ The next day John was there again with two of his disciples. ³⁶ When he saw Jesus walking by, he said, “Look, the Lamb of God!” ³⁷ And when the two disciples heard him say this, they followed Jesus. ³⁸ Jesus turned and saw them following. “What do you want?” He asked. They said to Him, “Rabbi” (which means Teacher), “where are You staying?” ³⁹ “Come and see,” He replied. So they went and saw where He was staying, and spent that day with Him. It was about the tenth hour.

Word study "Rabbi" — Rabbi (John 1:38, 49)

Greek: ῥαββί (Rabbi), pronounced rab-BEE. Strong’s G4461.

Rabbi is a Greek transliteration of a Hebrew word meaning, literally, “my great one” or “my master” — the honorific title for a recognized teacher of the Torah. John, writing for readers who do not know the term, pauses to translate it: Rabbi “which means Teacher” (1:38). Its use here is significant: the two disciples who leave John the Baptist do not address Jesus as a casual acquaintance but as master — they are placing themselves under Him as students. In the rabbinic world a disciple did not enroll in a course; he attached himself to a teacher’s whole life, walking where he walked, learning by being near. When Nathanael later cries “Rabbi, You are the Son of God!” (1:49), the title has been filled to overflowing — the Teacher is the King.

Word study "Remain / abide / stay" — menō (John 1:38–39)

Greek: μένω (menō), pronounced MEN-oh. Strong’s G3306.

Menō means “to remain, stay, abide, dwell, continue.” On the surface in this passage it is almost mundane — the two disciples ask Jesus, “Where are You staying (meneis)?”, and “they… saw where He was staying” (menei) and “spent that day with Him” (1:38–39). But menō is one of John’s great theological words, sounded here for the first time and developed all the way to the vine of chapter 15: “Remain (meinate) in Me, and I will remain in you” (John 15:4). What begins as a question about an address becomes, by the Gospel’s end, the very word for union with Christ. The first disciples ask where Jesus is staying; the whole Gospel is an invitation to stay with Him — to abide.

“The next day” again — the third day of the chapter — and now the testimony does its work. John repeats the cry, shorter this time: “Look, the Lamb of God!” And his own two disciples, hearing it, follow Jesus. This is the witness’s joy, not his loss: he exists precisely so that people will leave him for the One he names. Jesus’ first recorded words in this Gospel are a question that searches every heart: “What do you want?”what are you seeking? The disciples answer with a question of their own, and they call Him “Rabbi” (rab-BEE), Teacher, placing themselves under Him: “where are You staying?” (meneis, MEN-oh) — where do You abide? Jesus’ reply is the great invitation of the chapter: “Come and see.” No argument, no credentials demanded — just come, and look for yourself. They go, they see where He stays (menei), and they stay with Him the rest of the day. The detail “about the tenth hour” is the fingerprint of memory — late afternoon, an hour one of these two (almost certainly John himself) never forgot. The word for staying is quiet now, but it is the seed of everything: to find Jesus is to be invited to abide.

John 1:40–42 (BSB)

⁴⁰ Andrew, Simon Peter’s brother, was one of the two who heard John’s testimony and followed Jesus. ⁴¹ He first found his brother Simon and told him, “We have found the Messiah” (which is translated as Christ). ⁴² Andrew brought him to Jesus, who looked at him and said, “You are Simon son of John. You will be called Cephas” (which is translated as Peter).

Word study "Christ" / "Messiah" — Christos (John 1:41)

Greek: Χριστός (Christos), pronounced khris-TOS. Strong’s G5547.

Christos means “the Anointed One” — the exact Greek equivalent of the Hebrew Māšîaḥ, “Messiah.” Both words come from the act of anointing with oil, the ceremony by which Israel set apart its kings, priests, and prophets for God’s service (1 Samuel 16:13). By the first century, the Anointed One had become the title for the long-promised deliverer from David’s line who would come to rescue and reign. John makes the two words touch in a single verse: Andrew runs to Simon and says, “We have found the Messiah” — and the Evangelist immediately glosses it for his Greek readers, “which is translated as Christos” (1:41). The Hebrew hope and the Greek word meet in one Person. To confess Jesus as Christos is not to give Him a surname; it is to say the centuries of longing have arrived.

One of the two is named: Andrew. And the very first thing Andrew does, having spent an afternoon with Jesus, is the most natural thing in the Gospel — “He first found his brother Simon” and announced, “We have found the Messiah” (Christos, khris-TOS). The chain of testimony that began with John the Baptist now runs through an ordinary fisherman to his brother. Notice the method: Andrew does not debate Simon; he brings him — “Andrew brought him to Jesus.” And Jesus, meeting Simon for the first time, looks at him — the Greek suggests a penetrating, knowing gaze — and renames him: “You are Simon son of John. You will be called Cephas” (Aramaic for rock), “which is translated as Peter.” To rename someone in Scripture is to lay claim to their future. Jesus sees not only who Simon is but who he will become, and speaks the new name before there is anything rocklike about him. Grace names us by our destiny, not our track record.

John 1:43–46 (BSB)

⁴³ The next day Jesus decided to set out for Galilee. Finding Philip, He told him, “Follow Me.” ⁴⁴ Now Philip was from Bethsaida, the same town as Andrew and Peter. ⁴⁵ Philip found Nathanael and told him, “We have found the One Moses wrote about in the Law, the One the prophets foretold—Jesus of Nazareth, the son of Joseph.” ⁴⁶ “Can anything good come from Nazareth?” Nathanael asked. “Come and see,” said Philip.

Now Jesus takes the initiative: “Finding Philip, He told him, ‘Follow Me.’” The pattern alternates beautifully — disciples seek Jesus, and Jesus seeks disciples; both are true, and neither cancels the other. And Philip, like Andrew before him, immediately becomes a witness: he finds Nathanael and frames Jesus in the grandest possible terms — “the One Moses wrote about in the Law, the One the prophets foretold” — the fulfillment of the entire Hebrew Scriptures. But then he adds the homely, almost deflating detail: “Jesus of Nazareth, the son of Joseph.” And Nathanael’s reply is the honest skepticism of a man who knows the map: “Can anything good come from Nazareth?” — an obscure, unremarkable village the prophets never mentioned. Philip does not argue the geography. He simply repeats the invitation that has carried the whole chapter: “Come and see.” The cure for honest doubt is not a better argument but a personal encounter. Bring the doubter to Jesus and let Jesus do the rest.

John 1:47–51 (BSB)

⁴⁷ When Jesus saw Nathanael approaching, He said of him, “Here is a true Israelite, in whom there is no deceit.” ⁴⁸ “How do You know me?” Nathanael asked. Jesus replied, “Before Philip called you, I saw you under the fig tree.” ⁴⁹ “Rabbi,” Nathanael answered, “You are the Son of God! You are the King of Israel!” ⁵⁰ Jesus said to him, “Do you believe just because I told you I saw you under the fig tree? You will see greater things than these.” ⁵¹ Then He declared, “Truly, truly, I tell you, you will all see heaven open and the angels of God ascending and descending on the Son of Man.”

Jesus greets the skeptic with a compliment that is also a revelation: “Here is a true Israelite, in whom there is no deceit.” The phrase carries a quiet echo — Israel was the name given to Jacob, the deceiver (Genesis 27:35), and here is a son of Israel with none of Jacob’s guile. Nathanael, startled, asks how Jesus could possibly know him, and Jesus answers with a glimpse of His own omniscience: “Before Philip called you, I saw you under the fig tree.” What happened under that fig tree we are not told — but Nathanael clearly knows that he was seen where no human eye could have seen him, and the skeptic collapses into confession: “Rabbi” (rab-BEE), “You are the Son of God! You are the King of Israel!” The man who minutes earlier sneered at Nazareth now crowns its citizen. Jesus, almost gently, tells him this is only the beginning — “You will see greater things than these” — and then speaks the chapter’s final, towering word. Reaching back to Jacob’s ladder (Genesis 28:12), where heaven touched earth at Bethel, Jesus says: you will see heaven open and the angels of God ascending and descending on the Son of Man. The ladder Jacob dreamed was a Person all along. Jesus Himself is the open heaven, the meeting-place of God and humanity, the true house of God and gate of heaven. The chapter that began “In the beginning was the Word” ends with the Word standing on earth as the very stairway between worlds — and the invitation to come and see now opens onto heaven itself.

Study notes Going deeper

This passage gathers several of the Gospel’s master themes as the first disciples are drawn in. Watch them surface:

  • The faithful witness. John the Baptist’s greatness is measured entirely by his self-effacement. He answers “I am not” three times (1:20–21), names himself only as a voice (1:23), declares himself unworthy even to untie Jesus’ sandal (1:27), and gladly watches his own disciples leave him for Jesus (1:35–37). The model witness adds nothing to himself and points wholly away.
  • The Lamb who takes away sin. The single clearest statement of Jesus’ mission in the chapter (1:29). Before any miracle, any teaching, the witness names what Jesus came to do: bear away the world’s sin as the sacrificial Lamb.
  • “Come and see.” The recurring invitation (1:39, 46) that becomes the Gospel’s whole method of discipleship — personal, unforced, introducing rather than arguing.
  • Nathanael’s confession. The doubter who scoffs “Can anything good come from Nazareth?” (1:46) becomes, within minutes of meeting Jesus, the one who confesses Him “the Son of God… the King of Israel” (1:49). Honest skepticism is no barrier to a true encounter.
  • Jesus the true meeting-place of heaven and earth. The chapter closes on the promise that Jesus is Jacob’s ladder (1:51) — the one point where heaven stands open and God and humanity meet.

Three passages stand behind this day and are worth holding open beside it:

"He was oppressed and afflicted, yet He did not open His mouth. He was led like a lamb to the slaughter, and as a sheep before her shearers is silent, so He did not open His mouth." Isaiah 53:7 (BSB)

This is the prophecy beneath John’s cry. When he points and says “the Lamb of God,” he is announcing that the silent, suffering Lamb Isaiah foresaw has arrived in person.

"And Jacob had a dream about a ladder that rested on the earth with its top reaching up to heaven, and the angels of God were going up and down the ladder." Genesis 28:12 (BSB)

Jesus’ final words to Nathanael (1:51) rewrite this dream around Himself. The ladder between heaven and earth is no longer a vision at Bethel but a Person.

"For you know that it was not with perishable things such as silver or gold that you were redeemed from the empty way of life handed down to you by your forefathers, but with the precious blood of Christ, a lamb without blemish or spot." 1 Peter 1:18–19 (BSB)

Peter — one of the very men called in this chapter — later writes the meaning of John’s word amnos into the church’s confession: the Lamb of God is the spotless sacrifice whose blood redeems.

Personal Application

  1. “Among you stands One you do not know.” John’s questioners were so busy auditing his credentials that they missed the One standing in their midst. Where might you be examining the wrong things — credentials, arguments, qualifications — while Jesus stands nearer than you have noticed? What would it take today simply to recognize Him already present?

  2. “Come and see.” No one in this chapter was argued into faith; each was invited and then encountered Jesus for himself. Who in your life are you tempted to debate or pressure, when what they really need is an invitation to come and see — and is there a place where you yourself are still standing at a distance, hesitant to come and look closely?

  3. “Can anything good come from Nazareth?” Nathanael’s honest doubt did not disqualify him; it became the doorway to confession. What skepticism or hesitation have you assumed puts you outside the reach of God? What might happen if, instead of resolving the doubt first, you brought it with you and came to see?

Pray to Close

The central truth of this passage: the faithful witness points entirely away from himself to Jesus — the Lamb of God who takes away the sin of the world — and the Gospel’s whole method is an open invitation: come and see, and abide with the One who is Himself the meeting-place of heaven and earth. John pointed; the disciples came; and the heavens opened over the Son of Man.

Praise — the Lamb of God who takes away the sin of the world, the King of Israel, the open heaven where God and humanity meet.

Confess — the times you have kept Jesus at the edge of the crowd, examined Him from a distance, or let a “can anything good come from there?” keep you from coming close.

Ask — that the Holy Spirit would make you both a hearer who comes and sees, and a witness who, like Andrew, simply brings someone else to Jesus.


Worship for Today

Behold the Lamb (Communion Hymn) · Keith & Kristyn Getty and Stuart Townend (Official Lyric Video)

When John the Baptist pointed and cried “Look, the Lamb of God, who takes away the sin of the world!” (1:29), he was naming both the Passover lamb and Isaiah’s suffering Servant in a single breath. The Gettys’ communion hymn takes that very cry and sets it at the Lord’s Table, where the Lamb’s body and blood are remembered. Its opening line is John 1:29 turned into worship:

“Behold the Lamb who bears our sins away, Slain for us — and we remember The promise made that all who come in faith Find forgiveness at the cross.”

Where John pointed to the living Lamb walking toward him, the hymn looks back to the cross where that Lamb was “slain for us,” and forward to every table where the church still proclaims His death until He comes. “All who come in faith” is John’s “come and see” carried to its destination — the invitation that began at Bethany beyond the Jordan ends in fellowship around the Lamb who took away the sin of the world. Let the song put John’s cry on your own lips: behold the Lamb.
