Exercise is the number 1 ingredient of good physical health. And the Army, because of the large number of post traumatic stress cases, now administer a Spiritual Fitness Test. The rationale is simple - if the soldiers are to face the stress of war, there must be a spiritual component in their lives. As Christians, we are exhorted to grow and become more like Christ. Our salvation was never intended to be static. It was intended to make us more Christlike now - in this life.
