John 7:16-18

16 Jesus answered them and said, "My doctrine is not Mine, but His who sent Me.

17 If anyone wants to do His will, he shall know concerning the doctrine, whether it is from God or whether I speak on My own authority.

18 He who speaks from himself seeks his own glory; but He who seeks the glory of the One who sent Him is true, and no unrighteousness is in Him.
