Romans 7:13-20

13Did that which is good, then, become death to me? By no means! Nevertheless, in order that sin might be recognized as sin, it used what is good to bring about my death, so that through the commandment sin might become utterly sinful. 14We know that the law is spiritual; but I am unspiritual, sold as a slave to sin. 15I do not understand what I do. For what I want to do I do not do, but what I hate I do. 16And if I do what I do not want to do, I agree that the law is good. 17As it is, it is no longer I myself who do it, but it is sin living in me. 18For I know that good itself does not dwell in me, that is, in my sinful nature. Or my flesh For I have the desire to do what is good, but I cannot carry it out. 19For I do not do the good I want to do, but the evil I do not want to do—this I keep on doing.

20Now if I do what I do not want to do, it is no longer I who do it, but it is sin living in me that does it.
