"But the natural man does not receive the things of the Spirit of God... And I, brethren, could not speak to you as to spiritual people but as to carnal, as to babes in Christ."
1 CORINTHIANS 2:14, 3:1
THE UNCOMFORTABLE REALITY
Paul identifies three categories of human beings — not based on moral behaviour, but based on which part of them is governing. The natural man is governed by the flesh with no spiritual life. The carnal man has been born again but is still governed by the soul. The spiritual man is governed by the spirit where Christ dwells. Most Christians assume they are spiritual because they are saved. Paul says the Corinthians were saved — and carnal. Birth determines category one. Source determines the other two.
THE UNCOMFORTABLE QUESTION
The Corinthians were saved. They spoke in tongues. They had spiritual gifts. They attended gatherings. And Paul called them carnal.
Spiritual gifts do not prove spiritual maturity. Church attendance does not prove spiritual life. Biblical knowledge does not prove the spirit is governing.
The only evidence of the spiritual man is the fruit of a life governed by the Spirit — not the activity of a soul decorated with religious accessories.
