Romans 7:21-25

So I find it to be a law that when I want to do what is good, evil lies close at hand. For I delight in the law of God in my inmost self, 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. Wretched man that I am! Who will rescue me from this body of death? Thanks be to God through Jesus Christ our Lord! So then, with my mind I am a slave to the law of God, but with my flesh I am a slave to the law of sin.
