Romans 7:13-15

13Has then what is good become death to me? Certainly not! But sin, that it might appear sin, was producing death in me through what is good, so that sin through the commandment might become exceedingly sinful.

14For we know that the law is spiritual, but I am carnal, sold under sin.

15For what I am doing, I do not understand. For what I will to do, that I do not practice; but what I hate, that I do.
