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. 2TT 534.3
The tidings of every successful effort on our part to dispel the darkness and to diffuse the light and knowledge of God and of Jesus Christ, whom He has sent, are borne upward. The act is presented before the heavenly intelligences and thrills through all the principalities and powers, enlisting the sympathy of all heavenly beings. 2TT 535.1

As long as probation continues, there will be opportunity for the canvasser to work.—1900, Testimonies for the Church 6:478. 2TT 535.2
