Romans 7:20-23

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. So I find this law at work: although I want to do good, evil is right there with me. For in my inner being I delight in God’s law; but I see another law at work in me, waging war against the law of my mind and making me a prisoner of the law of sin at work within me.
