The matter of presenting true principles of health and temperance must not be passed over as unessential; for nearly every family needs to be instructed on this point. Nearly every person needs to have his conscience aroused to become a doer of the Word of God, practicing self-denial, and abstaining from the unlawful indulgence of appetite. When you make the people intelligent concerning the principles of health reform you do much to prepare the way for the introduction of present truth. Said my Guide, “Educate, educate, educate.” The mind must be enlightened, for the understanding of the people is darkened. Satan can find access to the soul through perverted appetite, to debase and destroy it.—Letter 1, 1875. (Ev 515.1) MC VC

Firmly Linked With Ministry of the Word—The principles of health reform are found in the Word of God. The gospel of health is to be firmly linked with the ministry of the Word. It is the Lord’s design that the restoring influence of health reform shall be a part of the last great effort to proclaim the gospel message.—Medical Ministry, 259 (1899). (Ev 515.2) MC VC

In Many Places—As a means of overcoming prejudice and gaining access to minds, medical missionary work must be done, not in one or two places only, but in many places where the truth has not yet been proclaimed. We are to work as gospel medical missionaries, to heal the sin-sick souls by giving them the message of salvation. This work will break down prejudice as nothing else can.—Testimonies For The Church 9:211 (1909). (Ev 515.3) MC VC

Necessary to the Advancement of the Cause—Medical missionary work is the right hand of the gospel. It is necessary to the advancement of the cause of God. As through it men and women are led to see the importance of right habits of living, the saving power of the truth will be made known. Every city is to be entered by workers trained to do medical missionary work. As the right hand of the third angel’s message, God’s methods of treating disease will open doors for the entrance of present truth.—Testimonies For The Church 7:59 (1902). (Ev 515.4) MC VC
