Romans 7:8

8. Wrought… concupiscence Commentators generally understand that the apostle here describes the reaction that sometimes takes place, with which the fractious soul sins the worse from its very spite against the restraints of law. It will not only sin when it is forbidden, but sin all the more rampantly because it is forbidden. Prohibition provokes transgression, and transgression ramps and rages out of vengeance against prohibition. Now this may be the meaning; and yet the idea seems hardly called for, or relevant to the train of thought. The demanded meaning is that sin, by means of law, brought every variety of concupiscence or unlawful heart-sin into revelation and visible existence; for the apostle more than once vividly describes a bringing into sight as a bringing into existence.

Dead Dead to all visibility or phenomenal existence.
