Romans 7:15, 18-20

I don’t really understand myself, for I want to do what is right, but I don’t do it. Instead, I do what I hate.

And I know that nothing good lives in me, that is, in my sinful nature. I want to do what is right, but I can’t. I want to do what is good, but I don’t. I don’t want to do what is wrong, but I do it anyway. But if I do what I don’t want to do, I am not really the one doing wrong; it is sin living in me that does it.
