JC - Chapter 25

As Jesus taught in the temple, Jewish teachers marveled -

"...How knoweth this man letters, having never learned?"  (New Testament | John 7:15)

Knowing their thoughts, the Savior responded -

"...My doctrine is not mine, but his that sent me.
17 If any man will do his will, he shall know of the doctrine, whether it be of God, or whether I speak of myself.
18 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."  (New Testament | John 7:16 - 18)

Elder Talmage commented -

"His Teacher, greater even than Himself, was the Eternal Father, whose will He proclaimed. The test proposed to determine the truth of His doctrine was in every way fair, and withal simple; anyone who would earnestly seek to do the will of the Father should know of himself whether Jesus spoke truth or error.  The Master proceeded to show that a man who speaks on his own authority alone seeks to aggrandize himself. Jesus did not so; He honored His Teacher, His Father, His God, not Himself; and therefore was He free from the taint of selfish pride or unrighteousness. Moses had given them the law, and yet, as Jesus affirmed, none of them kept the law."

I believe this applies to all His leaders.
