Romans 7:14-18

For we know that the law is divinely inspired and comes from the spiritual realm, but I am a human being made of flesh and trafficked as a slave under sin’s authority. I’m a mystery to myself, for I want to do what is right, but end up doing what my moral instincts condemn. And if my behavior is not in line with my desire, my conscience still confirms the excellence of the law. And now I realize that it is no longer my true self doing it, but the unwelcome intruder of sin in my humanity. For I know that nothing good lives within the flesh of my fallen humanity. The longings to do what is right are within me, but willpower is not enough to accomplish it.
