15. For that which I work, I understand not. For I do not that good which I will; but the evil which I hate, that I do.
16. If then I do that which I will not, I consent to the law, that it is good.
17. Now then it is no more I that do it, but sin that dwelleth in me.
18. For I know that there dwelleth not in me, that is to say, in my flesh, that which is good. For to will, is present with me; but to accomplish that which is good, I find not.
19. For the good which I will, I do not; but the evil which I will not, that I do.
20. Now if I do that which I will not, it is no more I that do it, but sin that dwelleth in me.
21. I find then a law, that when I have a will to do good, evil is present with me.
