Romans 7:16-23

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. 21So I find this law at work: Although I want to do good, evil is right there with me. 22For in my inner being I delight in God’s law; 23but I see another law at work in me, waging war against the law of my mind and making me a prisoner of the law of sin at work within me.
