Controlling your Body
When you become a new person in Christ, old things do pass away and all things become new (2 Cor. 5:17). But that is true only in regard to your inward man. Your spirit being becomes new. When you were born again, your body didn’t change. It will always want to do things it’s not supposed to do.
If your body never wanted to do what’s wrong, Paul would not have had to say, “I keep my body under control.” You don’t have to keep something under control that doesn’t have a tendency to get out of control.
For instance, as long as your car is parked, you don’t have to control the direction it’s going. When you begin driving a car, you have to guide it with the steering wheel. If you don’t you will lose control of the vehicle.
Just as a steering wheel guides a car, your spirit needs to control your body. Otherwise, your body will control you.
