John 7:16-18

RKJNT(i) 16 Jesus answered them, and said, My teaching is not mine, but his who sent me. 17 If any man is willing to do his will, he shall know of the teaching, whether it is of God, or whether I speak from myself. 18 He who speaks from himself seeks his own glory: but he who seeks the glory of the one who sent him, he is true, and there is no unrighteousness in him.
