John 1:29

Commentary on John 1:29

1. The Text

John 1:29 (King James Version):
“The next day John seeth Jesus coming unto him, and saith, Behold the Lamb of God, which taketh away the sin of the world.”

2. Exegetical Commentary

2.1 Immediate Context in John 1

John 1[i] opens with a majestic theological prologue:

John 1:1 (KJV):
“In the beginning was the Word, and the Word was with God, and the Word was God.”

The chapter establishes Jesus Christ as the eternal Word, the true Light, and the One who reveals the Father. John the Baptist appears as a witness, not the Light himself, but the one who prepares the way.

By the time we reach verse 29, John has already denied being the Christ, Elijah, or “that prophet,” and has identified himself as:

John 1:23 (KJV):
“The voice of one crying in the wilderness, Make straight the way of the Lord.”

The stage is set for John’s climactic declaration when he sees Jesus approaching.

2.2 “Behold” — A Call to Attention and Faith

The word “Behold” is not casual. It is a summons. John is directing the gaze of Israel, and indeed the world, away from himself and toward Jesus Christ. In Christian theology, this is the essence of gospel ministry: pointing away from human effort and toward the sufficiency of Christ.

2.3 “The Lamb of God” — The Fulfilment of Scripture

John’s title for Jesus is rich with Old Testament resonance.

2.3.1 The Passover Lamb

Exodus 12:13 (KJV):
“When I see the blood, I will pass over you.”

The Passover lamb’s blood shielded Israel from judgement. Jesus is the true and final Passover Lamb whose blood secures deliverance from God’s righteous wrath.

2.3.2 The Daily Sacrifice

Morning and evening lambs were offered for the sins of the people (Exodus 29:38–42). Jesus fulfils the continual need for atonement in one perfect sacrifice.

2.3.3 The Suffering Servant

Isaiah 53:7 (KJV):
“He is brought as a lamb to the slaughter.”

Isaiah’s prophecy finds its fulfilment in Jesus, the innocent sufferer who bears the sins of many.

2.3.4 God’s Provision for Abraham

Genesis 22:8 (KJV):
“God will provide himself a lamb for a burnt offering.”

In Jesus, God provides not merely a lamb, but His own Lamb.

2.4 “Which taketh away the sin of the world” — The Scope and Power of Christ’s Work

2.4.1 “Taketh away”

The verb indicates active, ongoing, effective removal. Jesus does not merely cover sin; He carries it away, bearing it in His own body on the cross.

2.4.2 “The sin of the world”

This phrase does not teach universal salvation, but the universal scope of Christ’s saving work. The Lamb is not for Israel alone. He is the Saviour of people from every tribe, language, and nation.

This aligns with the Christian understanding of the sufficiency of Christ’s atonement for all, and the efficacy of that atonement for the elect.

3. Theological Teaching

3.1 Christ-Centred Salvation

John’s declaration places Jesus at the centre of God’s saving plan. Salvation is not achieved through human effort, moral improvement, or religious ritual. It is grounded entirely in the person and work of Jesus Christ.

3.2 The Necessity of Atonement

Sin is not a small matter. It requires removal, cleansing, and judgement. The Lamb of God deals with sin decisively and completely.

3.3 The Universality of the Gospel Call

John’s words anticipate the global mission of the church. The gospel is for the world. The church is called to proclaim Christ to all people without distinction.

3.4 The Humility of Gospel Ministry

John models the posture of every faithful Christian leader:
not drawing attention to oneself, but pointing others to Christ.

4. Meditation Guide

4.1 Reflective Reading

Read John 1 slowly, paying attention to the identity of Jesus as the Word, the Light, and the Lamb. Let the chapter shape your understanding of who Christ is.

4.2 Personal Reflection Questions

• Where am I tempted to look for salvation, identity, or security apart from Christ?
• Do I behold Jesus with the same urgency and wonder that John expresses?
• How does knowing Jesus as the Lamb of God deepen my gratitude for His sacrifice?
• In what ways can I point others to Christ rather than to myself?

4.3 Prayer Suggestions

• Thank God for providing His own Lamb to take away your sin.
• Ask for a renewed sense of awe at the cost of your salvation.
• Pray for opportunities to direct others toward Jesus with clarity and humility.

4.4 Practical Application

• Cultivate habits that keep your attention fixed on Christ: regular Scripture reading, prayer, and participation in gathered worship.
• Practise humility in your relationships, seeking to elevate Christ rather than yourself.
• Share the gospel with confidence, knowing that Jesus is the Lamb for the world.

[i] John 1

King James Version

1 In the beginning was the Word, and the Word was with God, and the Word was God.

2 The same was in the beginning with God.

3 All things were made by him; and without him was not any thing made that was made.

4 In him was life; and the life was the light of men.

5 And the light shineth in darkness; and the darkness comprehended it not.

6 There was a man sent from God, whose name was John.

7 The same came for a witness, to bear witness of the Light, that all men through him might believe.

8 He was not that Light, but was sent to bear witness of that Light.

9 That was the true Light, which lighteth every man that cometh into the world.

10 He was in the world, and the world was made by him, and the world knew him not.

11 He came unto his own, and his own received him not.

12 But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name:

13 Which were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God.

14 And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth.

15 John bare witness of him, and cried, saying, This was he of whom I spake, He that cometh after me is preferred before me: for he was before me.

16 And of his fulness have all we received, and grace for grace.

17 For the law was given by Moses, but grace and truth came by Jesus Christ.

18 No man hath seen God at any time, the only begotten Son, which is in the bosom of the Father, he hath declared him.

19 And this is the record of John, when the Jews sent priests and Levites from Jerusalem to ask him, Who art thou?

20 And he confessed, and denied not; but confessed, I am not the Christ.

21 And they asked him, What then? Art thou Elias? And he saith, I am not. Art thou that prophet? And he answered, No.

22 Then said they unto him, Who art thou? that we may give an answer to them that sent us. What sayest thou of thyself?

23 He said, I am the voice of one crying in the wilderness, Make straight the way of the Lord, as said the prophet Esaias.

24 And they which were sent were of the Pharisees.

25 And they asked him, and said unto him, Why baptizest thou then, if thou be not that Christ, nor Elias, neither that prophet?

26 John answered them, saying, I baptize with water: but there standeth one among you, whom ye know not;

27 He it is, who coming after me is preferred before me, whose shoe’s latchet I am not worthy to unloose.

28 These things were done in Bethabara beyond Jordan, where John was baptizing.

29 The next day John seeth Jesus coming unto him, and saith, Behold the Lamb of God, which taketh away the sin of the world.

30 This is he of whom I said, After me cometh a man which is preferred before me: for he was before me.

31 And I knew him not: but that he should be made manifest to Israel, therefore am I come baptizing with water.

32 And John bare record, saying, I saw the Spirit descending from heaven like a dove, and it abode upon him.

33 And I knew him not: but he that sent me to baptize with water, the same said unto me, Upon whom thou shalt see the Spirit descending, and remaining on him, the same is he which baptizeth with the Holy Ghost.

34 And I saw, and bare record that this is the Son of God.

35 Again the next day after John stood, and two of his disciples;

36 And looking upon Jesus as he walked, he saith, Behold the Lamb of God!

37 And the two disciples heard him speak, and they followed Jesus.

38 Then Jesus turned, and saw them following, and saith unto them, What seek ye? They said unto him, Rabbi, (which is to say, being interpreted, Master,) where dwellest thou?

39 He saith unto them, Come and see. They came and saw where he dwelt, and abode with him that day: for it was about the tenth hour.

40 One of the two which heard John speak, and followed him, was Andrew, Simon Peter’s brother.

41 He first findeth his own brother Simon, and saith unto him, We have found the Messias, which is, being interpreted, the Christ.

42 And he brought him to Jesus. And when Jesus beheld him, he said, Thou art Simon the son of Jona: thou shalt be called Cephas, which is by interpretation, A stone.

43 The day following Jesus would go forth into Galilee, and findeth Philip, and saith unto him, Follow me.

44 Now Philip was of Bethsaida, the city of Andrew and Peter.

45 Philip findeth Nathanael, and saith unto him, We have found him, of whom Moses in the law, and the prophets, did write, Jesus of Nazareth, the son of Joseph.

46 And Nathanael said unto him, Can there any good thing come out of Nazareth? Philip saith unto him, Come and see.

47 Jesus saw Nathanael coming to him, and saith of him, Behold an Israelite indeed, in whom is no guile!

48 Nathanael saith unto him, Whence knowest thou me? Jesus answered and said unto him, Before that Philip called thee, when thou wast under the fig tree, I saw thee.

49 Nathanael answered and saith unto him, Rabbi, thou art the Son of God; thou art the King of Israel.

50 Jesus answered and said unto him, Because I said unto thee, I saw thee under the fig tree, believest thou? thou shalt see greater things than these.

51 And he saith unto him, Verily, verily, I say unto you, Hereafter ye shall see heaven open, and the angels of God ascending and descending upon the Son of man.
