Rom 7:7,13.   What shall we say then? Is the law sin? God forbid. Nay, I had not known sin, but by the law: for I had not known lust, except the law had said, Thou shalt not covet. ...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. Rom 3:20.   Therefore by the deeds of the law there shall no flesh be justified in his sight: for by the law is the knowledge of sin.
