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. CME 8.4
