John 7:16-18

16Jesus therefore answered them and said, My doctrine is not mine, but [that] of him that has sent me.

17If any one desire to practise his will, he shall know concerning the doctrine, whether it is of 1God, or [that] I speak from myself.

18He that speaks from himself seeks his own glory; but he that seeks the glory of him that has sent him, he is true, and unrighteousness is not in him.
