Romans 7

Romans 7:4-6 (KJV)
4 Wherefore, my brethren, ye also are become dead to the law by the body of Christ; that ye should be married to another, even to him who is raised from the dead, that we should bring forth fruit unto God.
5 For when we were in the flesh, the motions of sins, which were by the law, did work in our members to bring forth fruit unto death.
6 But now we are delivered from the law, that being dead wherein we were held; that we should serve in newness of spirit, and not in the oldness of the letter.

Romans 7:11-13 (KJV)
11 For sin, taking occasion by the commandment, deceived me, and by it slew me.
12 Wherefore the law is holy, and the commandment holy, and just, and good.
13 Was then that which is good made death unto me? God forbid. But sin, that it might appear sin, working death in me by that which is good; that sin by the commandment might become exceeding sinful.
