Romans 7:18-25

For I know that in me, that is, in my flesh, dwelleth no good thing: for to will is present with me, but to do that which is good is not. For the good which I would I do not: but the evil which I would not, that I practise. But if what I would not, that I do, it is no more I that do it, but sin which dwelleth in me. I find then the law, that, to me who would do good, evil is present. For I delight in the law of God after the inward man: but I see a different law in my members, warring against the law of my mind, and bringing me into captivity under the law of sin which is in my members. Wretched man that I am! who shall deliver me out of the body of this death? I thank God through Jesus Christ our Lord. So then I of myself with the mind, indeed, serve the law of God; but with the flesh the law of sin.
