Lead the people to study the manifestation of God’s love and wisdom in the works of nature.Lead them to study the marvelous organism, the human system, and the laws by which it is governed. Those who perceive the evidences of God’s love, who understand something of the wisdom and beneficence of His laws and the results of obedience, will come to regard their duties and obligations from an altogether different point of view. Instead of looking upon an observance of the laws of health as a matter of sacrifice or self-denial, they will regard it, as it really is, as an inestimable blessing.Counsels On Health 40.2

Every gospel worker should feel that the giving of instruction in the principles of healthful living is a part of his appointed work. Of this work there is great need, and the world is open for it.—The Ministry of Healing, 147 (1905). CH 40.3
