What Kind of Man Are You? Natural, Spiritual or Carnal

As Christians we tend to lump the people of this world into two categories: the saved and the lost; "the saints and the ain'ts." But Paul says in this text that there's really three categories of people:
(1) the natural man who is unregenerate and unsaved, who has no desire for the things of God or the word of God;
(2) the spiritual man who has been born-again and is walking in the power and conviction of the Holy Spirit and bearing fruit; and:
(3) the saint that lives like an "ain't" - the carnal Christian who either remains immature and never seems to grow up, or perhaps one who is a mature believer but who backslides and falls back into the sin that makes him miserable.
Whatever the cause of your carnality God has a remedy. But what you do with God's word determines what God will do with you. Regeneration and restoration both come through repentance.
