Our Mind Wants To Do Right, But Our Bodies Do Another! Why?

Romans 7:21 - 25

21So I find this law at work: Although I want to do good, evil is right there with me. 22For in my inner being I delight in God’s law; 23but 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. 24What a wretched man I am! Who will rescue me from this body that is subject to death? 25Thanks be to God, who delivers me through Jesus Christ our Lord!
