Second, when we go to God, sometimes he begins to change us and to make us different than we were before we went to him. But you’ll get into trouble if you make this an absolute. If you believe that every time you confess sin (pointed out by the law) to God, then he automatically gives you the power to obey, you’ll believe anything. Sometimes God will change us and sometimes he won’t.
