Romans 7:21-23

New Revised Standard Version, Anglicised Catholic Edition

²¹ So I find it to be a law that when I want to do what is good, evil lies close at hand. ²² For I delight in the law of God in my inmost self, ²³ but I see in my members another law at war with the law of my mind, making me captive to the law of sin that dwells in my members.
