In this lesson we want to see the impotence of our natural being in the things of God. The impotence is the insufficiency. We may be very sufficient in other things, but we do not have any sufficiency, competence, or power in the things of God.
The spirit of fallen mankind has been deadened (Eph. 2:1, 5a), so it is useless in the things of God.
First Corinthians 2:14 says, "But a soulish man does not receive the things of the Spirit of God, for they are foolishness to him and he is not able to know them because they are discerned spiritually." This verse shows that our soul neither receives the things of the Spirit of God nor is it able to know them. A soulish man is a natural man, one who allows his soul (including the mind, the emotion, and the will) to dominate his entire being and who lives by his soul, ignoring his spirit, not using his spirit, and even behaving as if he did not have a spirit (Jude 19). Such a man does not receive the things of the Spirit of God, and he is not able to know them. Rather, he rejects them.
