Just as overcrowded trees require transplanting for healthy growth, inactive church members need placement in active missionary fields to regain vigor.

Original passage

Trees that are crowded closely together do not grow healthfully and sturdily. The gardener transplants them that they may have room to develop. A similar work would benefit many of the members of large churches. They need to be placed where their energies will be called forth in active Christian effort. They are losing their spiritual life, becoming dwarfed and inefficient, for want of self-sacrificing labor for others. Transplanted to some missionary field, they would grow strong and vigorous.
