After these things, Jesus came with his disciples into the land of Judea. He stayed there with them, and baptized.
He said, Are you a teacher of Israel, and don't you know these things? Verily, verily, I say unto you, I am speaking of those things that I know, and I am testifying of those things that I have seen; and you do not receive my witness. If I have talked to you about earthly things, and you did not believe, how will you believe, if I tell you of heavenly things? ( John 3:10-12 )
