15. What I do, I do not understand. For I do not do what I want, but I do what I hate.
16. Now if I do what I do not want, I concur that the law is good.
17. So now it is no longer I who do it, but sin that dwells in me.
18. For I know that good does not dwell in me, that is, in my flesh. The willing is ready at hand, but doing the good is not.
19. For I do not do the good I want, but I do the evil I do not want.
20. Now if [I] do what I do not want, it is no longer I who do it, but sin that dwells in me.
21. So, then, I discover the principle that when I want to do right, evil is at hand.
22. For I take delight in the law of God, in my inner self,
23. but I see in my members another principle at war with the law of my mind, taking me captive to the law of sin that dwells in my members.
