[Testimonies for the Church 3:485-489 (1875).]
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. CH 122.1
The Redeemer of the world knew that the indulgence of appetite would bring physical debility and so deaden the perceptive organs that sacred and eternal things would not be discerned. Christ knew that the world was given up to gluttony, and that this indulgence would pervert the moral powers. If the indulgence of appetite was so strong upon the race that, in order to break its power, the divine Son of God, in behalf of man, was required to fast nearly six weeks, what a work is before the Christian in order that he may overcome even as Christ overcame! The strength of the temptation to indulge perverted appetite can be measured only by the inexpressible anguish of Christ in that long fast in the wilderness. CH 122.2
Christ knew that in order to successfully carry forward the plan of salvation He must commence the work of redeeming man just where the ruin began. Adam fell by the indulgence of appetite. In order to impress upon man his obligations to obey the law of God, Christ began His work of redemption by reforming the physical habits of man. The declension in virtue and the degeneracy of the race are chiefly attributable to the indulgence of perverted appetite. CH 122.3
