Romans 7:23-25

New King James Version

²³ But ^(A)I see another law in ^(B)my members, warring against the law of my mind, and bringing me into captivity to the law of sin which is in my members. ²⁴ O wretched man that I am! Who will deliver me ^(C)from this body of death? ^25 (D)I thank God—through Jesus Christ our Lord!

So then, with the mind I myself serve the law of God, but with the flesh the law of sin.
