John 7:15-17

Authorized (King James) Version

¹⁵ And the Jews marvelled, saying, How knoweth this man letters, having never learned? ¹⁶ Jesus answered them, and said, My doctrine is not mine, but his that sent me. ¹⁷ If any man will do his will, he shall know of the doctrine, whether it be of God, or whether I speak of myself.
