In House-to-House Ministry—Learn to sing the simplest of songs. These will help you in house-to-house labor, and hearts will be touched by the influence of the Holy Spirit.... We learn from the Word that there is joy among the angels over one repentant sinner, and that the Lord Himself rejoices over His church with singing.—The Review and Herald, November 11, 1902. {Ev 502.5}

Dør-til-dør arbejde - Lær at synge de enkleste sange. Disse vil hjælpe jer i dør-til-dør arbejdet, og hjerter vil blive berørt af Helligåndens indflydelse. . . . . Vi lærer fra Ordet at der er glæde blandt englene over den angrende synder, og at Herren selv glæder sin menighed (503) med sang. - Review and Herald, 11.nov. 1902.
