Canvassers should be able to give instruction in regard to the treatment of the sick. They should learn the simple methods of hygienic treatment. Thus they may work as medical missionaries, ministering to the souls and the bodies of the suffering. This work should now be going forward in all parts of the world. Thus multitudes might be blessed by the prayers and instruction of God’s servants. (6T 324.1) MC VC

We need to realize the importance of the canvassing work as one great means of finding out those who are in peril and bringing them to Christ. Canvassers should never be prohibited from speaking of the love of Christ, from telling their experience in their service for the Master. They should be free to speak or to pray with those who are awakened. The simple story of Christ’s love for man will open doors for them, even to the homes of unbelievers. (6T 324.2) MC VC

As the canvasser visits the people at their homes, he will often have opportunity to read to them from the Bible or from books that teach the truth. When he discovers those who are searching for truth he can hold Bible readings with them. These Bible readings are just what the people need. God will use in His service those who thus show a deep interest in perishing souls. Through them He will impart light to those who are ready to receive instruction. (6T 324.3) MC VC

Some who labor in the canvassing field have a zeal that is not according to knowledge. Because of their lack of wisdom, because they have been so much inclined to act the minister and theologian, it has been almost a necessity to place restrictions upon our canvassers. When the Lord’s voice calls, “Whom shall I send, and who will go for Us?” the Divine Spirit puts it into hearts to respond: “Here am I; send me.” Isaiah 6:8. But bear in mind that the live coal from the altar must first touch your lips. Then the words you speak will be wise and holy words. Then you will have wisdom to know what to say and what to leave unsaid. You will not try to reveal your smartness as theologians. You will be careful not to arouse a combative spirit or excite prejudice by introducing controverted points of doctrine. You will find enough to talk about that will not excite opposition, but that will open the heart to desire a deeper knowledge of God’s word. (6T 324.4) MC VC
