Ministers should work in cooperation with canvassers—I have been instructed that even where the people hear the message from the living preacher, the canvasser should carry on his work in co-operation with the minister; for though the minister may faithfully present the message, the people are not able to retain it all. The printed page is therefore essential, not only in awakening them to the importance of the truth for this time, but in rooting and grounding them in the truth and establishing them against deceptive error. Papers and books are the Lord's means of keeping the message for this time continually before the people. In enlightening and confirming souls in the truth the publications will do a far greater work than can be accomplished by the ministry of the Word alone. The silent messengers that are placed in the homes of the people through the work of the canvasser will strengthen the gospel ministry in every way; for the Holy Spirit will impress minds as they read the books, just as He impresses the minds of those who listen to the preaching of the Word. The same ministry of angels attends the books that contain the truth as attends the work of the minister.—Testimonies for the Church 6:315. PaM 110.1
The canvasser occupies a position equal to that of the gospel minister—The canvassing work is an important field for labor; and the intelligent, God-fearing, truth-loving canvasser occupies a position equal to that of the gospel minister. Then should the canvasser feel at liberty, any more than the ordained minister, to act from selfish motives? Should he be unfaithful to all the principles of missionary work, and sell only those books that are cheapest and easiest to handle, neglecting to place before the people the books which will give most light, because by so doing, he can earn more money for himself?—Testimonies to Ministers and Gospel Workers, 317, 318. PaM 110.2
Do not flatter good colporteurs into becoming poor ministers—In all parts of the field canvassers should be selected, not from the floating element in society, not from among men and women who are good for nothing else and have made a success of nothing, but from among those who have good address, tact, keen foresight, and ability. Such are needed to make a success as colporteurs, canvassers, and agents. Men suited to this work undertake it, but some injudicious minister will flatter them that their gift should be employed in the desk instead of simply in the work of the colporteur. Thus this work is belittled. They are influenced to get a license to preach; and the very ones who might have been trained to make good missionaries to visit families at their homes and talk and pray with them are caught up to make poor ministers; and the field where so much labor is needed, and where so much good might be accomplished for the cause, is neglected. The efficient colporteur, as well as the minister, should have a sufficient remuneration for his services if his work is faithfully done.—Testimonies for the Church 4:389. PaM 110.3
