John 7:16

Now about the midst of the feast Jesus went up into the temple, and taught.

And the Jews marvelled, saying, How knoweth this man letters, having never learned?

If any man will do his will, he shall know of the doctrine, whether it be of God, or whether I speak of myself.

He that speaketh of himself seeketh his own glory: but he that seeketh his glory that sent him, the same is true, and no unrighteousness is in him.
