Romans 7:15-25

For that which I do, I do not understand, and not even the good that I desire is what I do; but what I hate, that is what I do. If then I do that which I do not desire, I approve that the law is good. So that it is no longer I that do it, but sin that dwells in me. And I know that in me (that is, in my flesh) dwells no good thing; for I have the desire, but I am not able to perform that which is good. For I do not do the good that I desire; but the evil which I do not desire, that I do. And if I do that which I do not desire, I am not working, but sin that dwells in me. So that, desiring to do good, I find this law: evil is natural unto me. For I delight with the law of God with the inward man, but I see another law in my members which rebels against the law of my mind, bringing captive unto the law of sin which is in my members. O wretched man that I am! who shall deliver me from the body of this death? The grace of God, by Jesus, the Christ, our Lord. So then with the mind I myself serve the law of God, but with the flesh the law of sin.
