John 1:7

1:7 He came as a witness to testify about the light, so that everyone might believe through him.

John 1:26-36

1:26 John answered them, “I baptize with water. Among you stands one whom you do not recognize, 1:27 who is coming after me. I am not worthy to untie the strap of his sandal!” 1:28 These things happened in Bethany across the Jordan River where John was baptizing.

1:29 On the next day John saw Jesus coming toward him and said, “Look, the Lamb of God who takes away the sin of the world! 1:30 This is the one about whom I said, ‘After me comes a man who is greater than I am, because he existed before me.’ 1:31 I did not recognize him, but I came baptizing with water so that he could be revealed to Israel.”

1:32 Then John testified, “I saw the Spirit descending like a dove from heaven, and it remained on him. 1:33 And I did not recognize him, but the one who sent me to baptize with water said to me, ‘The one on whom you see the Spirit descending and remaining – this is the one who baptizes with the Holy Spirit.’ 1:34 I have both seen and testified that this man is the Chosen One of God.”

1:35 Again the next day John was standing there with two of his disciples. 1:36 Gazing at Jesus as he walked by, he said, “Look, the Lamb of God!”
