Romans 7:23-25
7:23 But I see a different law in my members waging war against the law of my mind and making me captive to the law of sin that is in my members.
7:24 Wretched man that I am! Who will rescue me from this body of death?
7:25 Thanks be to God through Jesus Christ our Lord! So then, I myself serve the law of God with my mind, but with my flesh I serve the law of sin.
