Because the carnal mind is enmity against God: for it is not subject to the law of God, neither indeed can be.
All Commentaries on Romans 8:7 Go To Romans 8
John Chrysostom
AD 407
Paul is not saying that it is impossible for a wicked person to become good but rather that it is impossible for one who continues in wickedness to be subject to God. For a person to change and become good and subject to God is easy…. If we give our souls up to the Spirit and persuade our flesh to recognize its proper position, we shall make our souls spiritual as well. But if we are lazy we shall make our souls carnal. For since it was not natural necessity which put the gift into us but freedom of choice, it now rests with us which way we shall choose to go.
