Romans 7:21

For the good that I would I do not: but the evil which I would not, that I do.

Now if I do that I would not, it is no more I that do it, but sin that dwelleth in me.

For I delight in the law of God after the inward man:

But I see another law in my members, warring against the law of my mind, and bringing me into captivity to the law of sin which is in my members.
