John 7:17-18 AMPC
If any man desires to do His will (God's pleasure), he will know (have the needed illumination to recognize, and can tell for himself) whether the teaching is from God or whether I am speaking from Myself and of My own accord and on My own authority.
He who speaks on his own authority seeks to win honor for himself. [He whose teaching originates with himself seeks his own glory.] But He Who seeks the glory and is eager for the honor of Him Who sent Him, He is true; and there is no unrighteousness or falsehood or deception in Him.
