Romans 7:23-25

New Revised Standard Version Catholic Edition

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. ²⁴ Wretched man that I am! Who will rescue me from this body of death? ²⁵ 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.
