Romans 7:15; Romans 7:18-19

15 For I do not understand my own actions. For xI do not do what I want, but I do the very thing I hate.

18 For I know that nothing good dwells ain me, that is, in my flesh. For I have the desire to do what is right, but not the ability to carry it out. 19 bFor I do not do the good I want, but the evil I do not want is what I keep on doing.
