John 1:29-31
1:29 On the next day John saw Jesus coming toward him and said, “Look, the Lamb of God who takes away the sin of the world!
1:30 This is the one about whom I said, ‘After me comes a man who is greater than I am, because he existed before me.’
1:31 I did not recognize him, but I came baptizing with water so that he could be revealed to Israel.”
