Romans 3:20
For no man will be justified in God's sight by works of the Law; for through the Law comes the consciousness of sin.
Romans 7:7-11
What shall we say then? Is the Law sin? Certainly not. On the contrary I should not have become acquainted with sin had it not been for the Law; for except the Law had repeatedly said, "Thou shalt not lust," I should never have known the sin of lust.
Galatians 2:19
For it is through law I died to law, in order to live to God.
Galatians 3:10-13
but a curse rests on those who have their root in the works of the Law; for it is written. Cursed is every one that continues not in all the things written in the Book of the Law, to do them.
