Ellen G. White, Counsels on Health, p. 577

“Eating has much to do with religion. The spiritual experience is greatly affected by the way in which the stomach is treated. Eating and drinking in accordance with the laws of health promote virtuous actions. But if the stomach is abused by habits that have no foundation in nature, Satan takes advantage of the wrong that has been done and uses the stomach as an enemy of righteousness, creating a disturbance which affects the entire being. Sacred things are not appreciated. Spiritual zeal diminishes. Peace of mind is lost. There is dissension, strife, and discord. Impatient words are spoken and unkind deeds are done; dishonest practices are followed and anger is manifested—and all because the nerves of the brain are disturbed by the abuse heaped on the stomach.”

Ellen G. White, Messages to Young People, p. 134

“He that is slow to anger is better than the mighty; and he that ruleth his spirit than he that taketh a city.” He has conquered self—the strongest foe man has to meet.”

“The highest evidence of nobility in a Christian is self-control. He who can stand unmoved amid a storm of abuse is one of God’s heroes.

To rule the spirit is to keep self under discipline; to resist evil; to regulate every word and deed by God’s great standard of righteousness. He who has learned to rule his spirit will rise above the slights, the rebuffs, the annoyances, to which we are daily exposed, and these will cease to cast a gloom over his spirit.”

“It is God’s purpose that the kingly power of sanctified reason, controlled by divine grace, shall bear sway in the lives of human beings. He who rules his spirit is in possession of this power.”
