"For I do not understand my own actions. For I do not do what I want, but I do the very thing I hate. Now if I do what I do not want, I agree that the law is good. So now it is no longer I who do it, but sin that dwells within me. For I know that nothing good dwells in me, that is, in my flesh. For I have the desire to do what is right, but not the ability to carry it out. For I do not do the good I want to do, but the evil I do not want to dothis I keep on doing. Now if I do what I do not want to do, it is no longer I who do it, but sin that dwells within me."
