Romans 3:20
Because no human creature can be brought into right standing with God by observing the law. For all the law can do is to make men conscious of sin.
Romans 7:7-11
What are we then to conclude? Is the law sin? Of course not! Yet, if it had not been for the law, I should not have learned what sin was, for I should not have known what an evil desire was, if the law had not said, "You must not have an evil desire."
Galatians 2:19
For through the law I myself have become dead to the law, so that I may live for God.
Galatians 3:10-13
For those who depend on what the law commands are under a curse, for the Scripture says, "Cursed be everyone who does not continue in all the commands that are written in the book of the law, to do them."
