Matthew Poole and continuators on 1 Corinthians 2:11

11 For what man knoweth the things of a man, save the spirit of a man that is in him? even so the things of God knoweth no man, but the Spirit of God .

Look as it is with a man, No man knoweth his secret thoughts, and counsels, and meanings, save only his own soul that is within him.

So it is as to the things of God, until God by his Spirit hath revealed them to men, none knoweth them but the holy Spirit of God. It is true as it is with man: when he hath by his tongue discovered his mind to others, they know it so far as he hath so delivered it; but there is no man that discovereth all his thoughts and counsels: so God having in his Word revealed his Will, so far as he hath plainly revealed it, men may know it; but there are deep things of God, Mysteries in Scripture, which till the Spirit of God hath revealed to men, they know not nor understand; for none knoweth them originally, but the Spirit of God, who is himself God, and searcheth the deep things of God.
