1 Corinthians 2:15

1 Corinthians 2:15 But the spiritual man discerns all things, but he himself is discerned by no one. 

A spiritual man is one who denies his soul and does not live by his soul but allows his spirit, that is, his regenerated spirit, which is occupied and energized by the Spirit of God, to dominate his entire being. Furthermore, he lives by such a spirit, moving and acting according to it. Such a spiritual person is able to discern the things of the Spirit of God because his constitutional capacity for spiritual perception is able to manifest its function.
