Romans 7:18-21

7:18 For I know that nothing good lives in me, that is, in my flesh. For I want to do the good, but I cannot do it. 7:19 For I do not do the good I want, but I do the very evil I do not want! 7:20 Now if I do what I do not want, it is no longer me doing it but sin that lives in me.

7:21 So, I find the law that when I want to do good, evil is present with me.
