I do not understand what I do. For what i want to do, i do not do. But what I do not want to do, I do. If I do what I do not want to do, I agree that the law is good. As it is, it is not I myself who does it but it is sin living in me. I know that nothing good lives in me, that is in my sinful nature. For I have the desire to do what is good but cannot carry it out. What I do is not the good I want to do, no, the evil I do not want to do, this I keep on doing. Now 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.
Romans 7:15-20
