Rather than doing no work and attempting to stir up a mob.
May God himself, the God of peace, sanctify you through and through.
May your whole spirit, soul and body be kept blameless at the coming
of our Lord Jesus Christ." 1 Thes 5:23
Regenerate man is trichotomous. Body, soul, and human spirit.
Unregenerate man is only dichotomous. Being only body and soul.
1 Corinthians 2:14 speaks of the dichotomous man, having no human spirit.
For what got termed "the natural man" in the Greek is psuchikos.
Psuchikos means 'soulish.' Having no human spirit! https://biblehub.com/greek/5591.htm
But the 'soulish' man receives not the things of the Spirit of God, for they are foolishness unto him;
neither can he know them, because they are spiritually discerned." 1 Cor 2:14
Also... The carnal believer cuts himself off from God's guiding spiritual fellowship with the Spirit, and he can end up rationalizing Scripture to suit his natural world view of religion. This carnal one becomes like "an informed" unbeliever in his inability to correctly think with Scripture.
