One of the strongest temptations that man has to meet is upon the point of appetite. Between the mind and the body there is a mysterious and wonderful relation. They react upon each other. To keep the body in a healthy condition to develop its strength, that every part of the living machinery may act harmoniously, should be the first study of our life. To neglect the body is to neglect the mind. It cannot be to the glory of God for His children to have sickly bodies or dwarfed minds. To indulge the taste at the expense of health is a wicked abuse of the senses. Those who engage in any species of intemperance, either in eating or drinking, waste their physical energies and weaken moral power. They will feel the retribution which follows the transgression of physical law.402Testimonies for the Church 3:485, 486 CCh 226.3
Many are incapacitated for labor both mentally and physically by overeating and the gratification of the lustful passions. The animal propensities are strengthened, while the moral and spiritual nature is enfeebled. When we shall stand around the great white throne, what a record will the lives of many then present. Then will they see what they might have done had they not debased their God-given powers. Then will they realize what height of intellectual greatness they might have attained had they given to God all the physical and mental strength He had entrusted to them. In their agony of remorse they will long to have their lives to live over again.403Testimonies for the Church 5:135 CCh 226.4
Every true Christian will have control of his appetite and passions. Unless he is free from the bondage and slavery of appetite he cannot be a true, obedient servant of Christ. It is the indulgence of appetite and passion which makes the truth of none effect upon the heart. It is impossible for the spirit and power of the truth to sanctify a man, soul, body, and spirit, when he is controlled by appetite and passion.404Testimonies for the Church 3:569, 570 CCh 226.5
The great end for which Christ endured that long fast in the wilderness was to teach us the necessity of self-denial and temperance. This work should commence at our tables and should be strictly carried out in all the concerns of life. The Redeemer of the world came from heaven to help man in his weakness, that, in the power which Jesus came to bring him, he might become strong to overcome appetite and passion, and might be victor on every point.405Testimonies for the Church 3:488 CCh 226.6
