John confessed that Jesus was greater than him for he (Jesus) had existed before him At first, John did not know Jesus, but he came baptising with water that Jesus might be revealed. The spirit of the Lord had told John that he would identify Jesus as the man on whom the spirit would descend. At the baptism of Jesus, the spirit descended as a dove from heaven and rested on him . John bore witness that Jesus is the son of God.
