Romans 7:23-25
23 but I see a different law in my members, warring against the law of my mind, and bringing me into captivity under the law of sin which is in my members.
24 Wretched man that I am! who shall deliver me out of the body of this death?
25 I thank God through Jesus Christ our Lord. So then I of myself with the mind, indeed, serve the law of God; but with the flesh the law of sin.
