Romans 7:15-16 "For what I am doing, I do not understand; for I am not practicing what I would like to do, but I am doing the very thing I hate. But if I do the very thing I do not want to do, I agree with the Law, confessing that the Law is good."

What an interesting verse.  Paul here is not condoning sin because we can't help it since our flesh is weak; instead he is arguing that when we do not want to do, or don't do what we want to do, we are agreeing with God's law.  We are saying that the law is good and we do not measure up!

Because of the law we have a knowledge of sin, and the conviction of the Spirit bears witness that the law is good.  The law is not invalidated because Christ has lifted the curse, instead we need the law.  Now more than ever.
