Charles Spurgeon Commentary John 7:18

"He that speaketh from himself seeketh his own glory: but he that seeketh the glory of him that sent him, the same is true, and no unrighteousness is in him." — John 7:18 (ASV)

If you ever hear a man speaking about the priesthood, meaning himself and his brothers; and about the Church, again meaning himself and his brothers; and about the sacraments, meaning certain performances by himself and his brothers; you may know at once that God did not send him. But he who speaks to the glory of God, and does not say, "Behold me;" but, Behold the Lamb of God, it is he whom God has sent.
