This is John's testimony when the Jewish leaders in Jerusalem sent priests and Levites to ask him, "Who are you?"
John confessed (he didn't deny but confessed), "I'm not the Christ."
They asked him, "Then who are you? Are you Elijah?" John said, "I'm not." "Are you the prophet?" John answered, "No."
They asked, "Who are you? We need to give an answer to those who sent us. What do you say about yourself?"
John replied, "I am a voice crying out in the wilderness, Make the Lord's path straight, just as the prophet Isaiah said."
Those sent by the Pharisees
asked, "Why do you baptize if you aren't the Christ, nor Elijah, nor the prophet?"
John answered, "I baptize with water. Someone greater stands among you, whom you don't recognize.
He comes after me, but I'm not worthy to untie his sandal straps."
This encounter took place across the Jordan in Bethany where John was baptizing.
The next day John saw Jesus coming toward him and said, "Look! The Lamb of God who takes away the sin of the world!
This is the one about whom I said, ‘He who comes after me is really greater than me because he existed before me.'
Even I didn't recognize him, but I came baptizing with water so that he might be made known to Israel."
John testified, "I saw the Spirit coming down from heaven like a dove, and it rested on him.
Even I didn't recognize him, but the one who sent me to baptize with water said to me, ‘The one on whom you see the Spirit coming down and resting is the one who baptizes with the Holy Spirit.'
I have seen and testified that this one is God's Son."
