Carnality is enmity to God
The scriptures let us to know that to be carnal is death and enemy to God you may ask, why, the scriptures says in romans 8:6b that to be spiritually minded is life and peace.
Yes to be carnally minded is enemy to God the reason is because romans 8:7 say Because the carnal mind is enmity against God: for it is not subject to the law of God, neither indeed can be. 8So then they that are in the flesh (carnal) cannot please God.
So living as a carnal man been ordinary is to be against the law of God, it means having no reverence for God.
God is the father of the world he is the creator of the supernatural realm, and then been carnal is going against the will of God because God created us human, and we are spirit living in a body.
So been carnal is abandoning the spirit of God and and living in the flesh finding pleasure in the flesh carnal cravings, attractions, satisfactions and urges, choking up with the affairs of this world. And the greatest enemy of man is the flesh the reason is because the devil satan find pleasures in the flesh it is only the flesh satan take hold off and penetrate through a man.
And we know that the enemy of God is satan, so been carnal is to be a child of the devil.
