"One of dignity and authority—One who is present in all our council meetings—was listening with deepest interest to every word. He spoke with deliberation and perfect assurance. “The whole world,” He said, “is God's great vineyard. The cities and villages constitute a part of that vineyard. These must be worked. Satan will try to interpose himself and discourage the workers, so as to prevent them from giving the message of light and warning in the more prominent as well as in the more secluded places. Desperate efforts will be made to turn the people from truth to falsehood. Angels of heaven are commissioned to co-operate with the efforts of God's appointed messengers on earth. Ministers must encourage and maintain an unwavering faith and hope, as did Christ, their living Head. They must keep humble and contrite in heart before God.” 7T 34.2"
"Then saith he unto his disciples, The harvest truly is plenteous, but the labourers are few;"
Both passages discuss the need for laborers in God's vineyard/harvest. The EGW passage expands on the difficulties and divine assistance involved, but the core idea is present in both.
