“Because the carnal mind is enmity against God: for it is not subject to the law of God, neither indeed can be.”
King James Version (KJV)
8:7 Enmity against God - His existence, power, and providence.
Ro 8:7 Because the carnal mind [is] enmity to God. Is opposed to God's law, and demand for a righteous life. Hence, since it fights against God, it is under condemnation. He does not say that it is impossible for a wicked man to become good, but that it cannot be done while he retains a carnal mind. He must be converted first.
