Romans 7:14-15, 18-19, 24-25

For we know that the law is spiritual: but I am carnal, sold under sin. For that which I do I know not: for not what I would, that do I practise; but what I hate, that I do.

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.

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.
