What? know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and ye are not your own? For ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God’s. 1 Cor. 6:19, 20.
That perfection of character which the Lord requires is the fitting up of the whole being as a temple for the indwelling of the Holy Spirit. God will accept of nothing less than the service of the entire human organism. It is not enough to bring into action certain parts of the living machinery. All parts must work in perfect harmony, or the service will be deficient. It is thus that man is qualified to cooperate with God in representing Christ to the world. Thus God desires to prepare a people to stand before Him pure and holy, that He may introduce them into the society of heavenly angels.
We have been entrusted with the most solemn message ever given to our world, and the object to be kept plainly and distinctly before our minds is the glory of God. Let us take care that we do nothing which will weaken physical, mental, or spiritual healthfulness, for God will not accept a tainted, diseased, corrupted sacrifice. Care must be exercised in eating, in drinking, in dressing, and in working, lest we detract from our efficiency and fail of doing our most exalted work in the best manner, in order that the results of our labor may be as lasting as eternity.
It is our duty to train and discipline the body in order that we shall render to the Master the highest possible service. Inclination must not control us. We are not to pamper the appetite and indulge in the use of that which is not for our good, simply because it gratifies the palate; neither are we to seek to live by the starvation plan, with the idea that we shall become spiritually-minded, and that God shall be glorified. We must use the intelligence that God has given in order that we may be perfect in body, soul, and spirit, that we may have a symmetrical character, a well-balanced mind, and do perfect work for the Master.
