The next day [John the Baptist] saw Jesus coming toward Him, and said, “Behold, the Lamb of God, who takes away the sin of the world!” … And John bore witness: “I saw the Spirit descend from heaven like a dove, and it remained on Him. I myself did not know Him, but He who sent me to baptize with water said to me, ‘He on whom you see the Spirit descend and remain, this is He who baptizes with the Holy Spirit.’ And I have seen and have borne witness that this is the Son of God.” (John 1:29, 32-34)
