(11-13) The cause of this miscarriage lay not with the Law but with Sin. Sin played the tempter, and then made use of the Commandment to condemn and destroy its victims. All this time the Law (i.e., the whole body of precepts) and the Commandment (i.e., the particular precepts included in the Law) remained perfectly good in themselves. They could not be otherwise, having come from the hand of God Himself. Sin was the fatal power. The Law and the Commandment were only passive instruments which it wielded for the destruction of man. But at the same time Sin itself was exposed by them in all its ever-increasing enormity.

Romans 7:11-13
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.
