We can compare our flesh to a test car in the wind tunnel. Our spirits are like the vapor that blows over the vehicle. If the car's shape changes even slightly, the vapor pattern will change. Likewise the composition of our spirit is dependent upon the inner workings of our flesh. Are you unhappy with your spirit at times? With the help and direction of the Creator, our spirit will change as we modify aspects of our character that have been habitually written into our flesh throughout our lifetime.
