At that time Jesus arrived from Galilee and came to John at the Jordan to be baptized by him.
But John tried to make him change his mind. "I ought to be baptized by you," John said, "and yet you have come to me!"
But Jesus answered him, "Let it be so for now. For in this way we shall do all that God requires." So John agreed.
As soon as Jesus was baptized, he came up out of the water. Then heaven was opened to him, and he saw the Spirit of God coming down like a dove and lighting on him.
Then a voice said from heaven, "This is my own dear Son, with whom I am pleased." 1
