No, I have never said the carnal man is subject to God's law. I have
repeatedly stated
he needs God's grace (which is real power at work) to overcome the flesh. How do you think you can walk as a Christian apart from God's grace to overcome the sin nature within? That nature has not gone anywhere, it still resides in the flesh but somehow you think God can't do that unless He first saves you. Powerful enough to do all that is required in salvation but not powerful enough to free you long enough to give you opportunity to respond from your own soul of your own volition. You do God no justice by such thinking.
The Gospel
is the power unto salvation. You have a man saved in order to be saved. You just can't or won't see it.
