"And every man that striveth for the mastery is temperate in all things" 1 Cor. 9:25.  This is both the counsel of love, and the command of love.  Self-discipline and self-control is one of the foundational principles in maintaining good health in your body - God's temple.  The Holy record goes on to state in 1 Cor. 9:27, "I keep under my body (discipline or subdue it) and bring it into subjection: lest that by any means, when I have preached to others, I myself should be a castaway."  Profession of being saved while one is not under the control of the spirit that gives them self-control, is a living misrepresentation, and a fatal deception.  As Christians, it is our heaven-ordained duty to maintain health by obedience to the laws of health.   The word "health" comes from the same root as the word "whole."  We often see the popular term "wholistic health."  The truth is, to be healthy is to be whole.  Wholistic health is wholeness, balance, and harmony in all three aspects of our being.  This includes the spiritual, the soul (which is the mental and emotional spheres) and the physical spheres of our being.  Here is where we need to deal specifically with the physical sphere of our being.  If one is physically sick it will always work to lessen one's mental progress and spiritual activities.  In almost all cases a sick man is less productive than the individual who is vibrant with wholistic health.   God would have his people healthy.  What do we need to know and to do to cooperate with God in maintaining this gift of health?
