His Spirit (tells us the manner of impartation of spiritual knowledge, which is Revelation): for the Spirit searches all things, yes, the deep things of God. (The Holy Spirit is the only One amply qualified to reveal God because He is God, and He is the member of the Godhead Who deals directly with man.) 11 For what man knows the things of a man, save the spirit of man which is in him? (The spirit of a man can know some things about another man, but within itself cannot know anything about God.)
