Romans 7:18-20

Yes, I know that nothing good lives in me—I mean nothing good lives in the part of me that is earthly and sinful. I want to do the things that are good, but I do not do them. I do not do the good things I want to do, but I do the bad things I do not want to do. So if I do things I do not want to do, then I am not the one doing them. It is sin living in me that does those things.
