John Wesley on 1 Corinthians 2:14

But the natural man - That is, every man who hath not the Spirit; who has no other way of obtaining knowledge, but by his senses and natural understanding. Receiveth not - Does not understand or conceive. The things of the Spirit - The things revealed by the Spirit of God, whether relating to his nature or his kingdom. For they are foolishness to him - He is so far from understanding, that he utterly despises, them Neither can he know them - As he has not the will, so neither has he the power. Because they are spiritually discerned - They can only be discerned by the aid of that Spirit, and by those spiritual senses, which he has not.
