We must educate, educate, educate, pleasantly and intelligently. We must preach the truth, pray the truth, and live the truth, bringing it with its gracious, health-giving influences within the reach of those who know it not. As the sick are brought into touch with the Life-giver their faculties of mind and body will be renewed. But in order for this to be, they must practice self-denial, and be temperate in all things. Thus only can they be saved from physical and spiritual death and restored to health. MM 262.3
When the human machinery moves in harmony with the life-giving arrangements of God, as brought to light through the gospel, disease is overcome and health springs forth speedily. When human beings work in union with the Life-giver, who offered up His life for them, happy thoughts fill the mind. Body and mind and soul are sanctified. Human beings learn of the Great Teacher, and all upon which they look ennobles and enriches the thoughts. The affections are drawn out in gladness and thankfulness to the Creator. The life of the man who is renewed in the image of Christ is as a light shining in darkness.—Letter 83, 1905. MM 262.4
