It is medical missionaries that are needed all through the field. Canvassers should improve every opportunity granted them to learn how to treat disease. Physicians should remember that they will often be required to perform the duties of a minister. Medical missionaries come under the head of evangelists. The workers should go forth two by two, that they may pray and consult together. Never should they be sent out alone. The Lord Jesus Christ sent forth His disciples two and two into all the cities of Israel. He gave them the commission, “Heal the sick that are therein, and say unto them, The kingdom of God is come nigh unto you.” MM 249.2
We are instructed in the word of God that an evangelist is a teacher. He should also be a medical missionary. But all are not given the same work. “He gave some, apostles; and some, prophets; and some, evangelists; and some, pastors and teachers; for the perfecting of the saints, for the work of the ministry, for the edifying of the body of Christ.” ... MM 249.3
Those who labor in our conferences as ministers should become acquainted with the work of ministering to the sick. No minister should be proud that he is ignorant where he should be wise. Medical missionary work connects man with his fellowmen and with God. The manifestation of sympathy and confidence is not to be limited by time or space.—Manuscript 33, 1901. MM 250.1
