John 7:14-17

14But when it was now the middle of the feast, Jesus went up into the temple and taught.

15The Jews therefore wondered, saying, How knows this [man] letters, having never learned?

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.
