The Lamb of God, who takes away the sin of the world

John 1:19-34

John said "I am the voice of one calling in the desert, 'Make straight the way for the Lord.'" in the words of Isaiah.
John baptized with water, Jesus baptize with Holy spirit.
When John saw Jesus next day and said "Look, the Lamb of God, who take away the sin of the world! This is the one I meant when I said."
John said "I would not have known him, except that the one who sent me to baptist with water told me, 'The man on whom you see the Spirit come down and remain is he who will baptize with the Holy Spirit.' I have seen and I testify that this is the son of God.
