Romans 7:15-19

For I do not understand what I am doing; for I am not practicing what I want to do, but I do the very thing I hate.

However, if I do the very thing I do not want to do, I agree with the Law, that the Law is good.

But now, no longer am I the one doing it, but sin that dwells in me.

For I know that good does not dwell in me, that is, in my flesh; for the willing is present in me, but the doing of the good is not.

For the good that I want, I do not do, but I practice the very evil that I do not want.
