Let the Spirit renew your thoughts and attitudes.- Ephesians 4:23. Change requires new thinking. In order to change, we must learn the truth and start making good choices but, but we also must change the way we think. The battle for sin starts in your mind, not in your behavior. The way you think determines the way you feel, and the way you feel determines the way you act. If you want to change the way you act, you start by changing the way you think. In addition if you want to change the way you feel, you must start with changing the way you think.
