Of equal importance with special public efforts is house-to-house work in the homes of the people. In large cities there are certain classes that cannot be reached by public meetings. These must be searched out as the shepherd searches for his lost sheep. Diligent, personal effort must be put forth in their behalf. When personal work is neglected, many precious opportunities are lost, which, were they improved, would advance the work decidedly. 9T 111.1
As the result of the presentation of the truth in large congregations, a spirit of inquiry is awakened, and it is especially important that this interest be followed up by personal labor.
