John 1:7-9, 15-17, 29, 34

He came as a witness, to bear witness about the light, that all might believe through him. He was not the light, but came to bear witness about the light. The true light, which gives light to everyone, was coming into the world.

(John bore witness about him, and cried out, “This was he of whom I said, ‘He who comes after me ranks before me, because he was before me.’”) For from his fullness we have all received, grace upon grace. For the law was given through Moses; grace and truth came through Jesus Christ.

The next day he saw Jesus coming toward him, and said, “Behold, the Lamb of God, who takes away the sin of the world!

And I have seen and have borne witness that this is the Son of God.”
