For what man knoweth the things of a man, save the spirit of man which is in him? even so the things of God knoweth no man, but the Spirit of God.
What man ... - literally, who of MEN knoweth the things of a MAN, except the spirit of that man?
Things of God knoweth no man - rather, 'none knoweth,' not angel or man.
But the Spirit of God. Supply, and he to whom the Spirit of God reveals them (so Matthew 11:27, end). Even in the case of man, so infinitely inferior to God, none of his fellow-men, but his own spirit alone, knows (whether that knowledge be great or small) what is within him. Man's spirit is the organ wherewith he receives God's Spirit, through Whom alone he can know God.
