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.
