Romans 7:20-23
20 Now if I do what I do not want to do, it is no longer I who do it, but it is sin living in me that does it.
21 So I find this law at work: When I want to do good, evil is right there with me.
22 For in my inner being I delight in God’s law;
23 but I see another law at work in the members of my body, waging war against the law of my mind and making me a prisoner of the law of sin at work within my members.
