John 1:29 (KJV)

What does John 1:29 mean?

John 1:29 describes John the Baptist seeing Jesus approach and announcing, “Behold the Lamb of God, which taketh away the sin of the world.” John is publicly identifying Jesus as someone chosen by God to remove the world’s sin, using the image of a sacrificial lamb.

John the Baptist is speaking to the crowd gathered by the Jordan River, where he has been baptizing people. By calling Jesus the “Lamb of God,” John draws on the familiar idea of a lamb offered in sacrifice, especially from Jewish traditions like Passover. John’s statement points to Jesus’ unique role in dealing with sin, not just for one group but for everyone.

The Greek behind John 1:29

• ἀμνὸς (amnos, “Lamb”): This word refers to a sacrificial lamb, often used in temple rituals. Calling Jesus the “Lamb of God” connects him to the idea of sacrifice for forgiveness.
• ἁμαρτίαν (hamartian, “sin”): The Greek word here is singular, suggesting the whole problem of sin, not just individual wrongs. John presents Jesus as dealing with sin at its root.
• κόσμου (kosmou, “world”): This word means the whole world or all humanity, not just Israel. John’s statement is broad, showing Jesus’ mission is for everyone, not a select few.

Why John 1:29 matters

• John the Baptist’s words clarify that Jesus’ purpose is tied to sacrifice and forgiveness, not just teaching or leadership.
• The verse emphasizes that Jesus’ mission is global—he is described as taking away the sin of the “world,” not just one nation or group.
• This moment sets the stage for the rest of John’s Gospel, introducing a key theme: Jesus as the one who deals with humanity’s deepest problem, sin, through God’s initiative.
