There is a solemn responsibility upon all, especially upon ministers who teach the truth, to overcome upon the point of appetite. Their usefulness would be much greater if they had control of their appetites and passions, and their mental and moral powers would be stronger if they combined physical labor with mental exertion. With strictly temperate habits, and with mental and physical labor combined, they could accomplish a far greater amount of labor and preserve clearness of mind. If they would pursue such a course, their thoughts and words would flow more freely, their religious exercises would be more energized, and the impressions made upon their hearers would be more marked. CH 123.1
Intemperance in eating, even of food of the right quality, will have a prostrating influence upon the system and will blunt the keener and holier emotions. Strict temperance in eating and drinking is highly essential for the healthy preservation and vigorous exercise of all the functions of the body. Strictly temperate habits, combined with exercise of the muscles as well as of the mind, will preserve both mental and physical vigor, and give power of endurance to those engaged in the ministry, to editors, and to all others whose habits are sedentary....
