Lamsa(i)
13 For the things which we discuss are not dependent on the knowledge of words and manÆs wisdom, but on the teaching of the Spirit; thus explaining spiritual things to the spiritually minded.
14 For the material man rejects spiritual things, for they are foolishness to him: neither can he know them, because they are spiritually discerned.
15 But the spiritual man discerns every thing, and yet no man can discern him.
