Ellen White's Earliest Appeal for Cities and Villages

The cities and villages constitute a part of [God's] vineyard. These must be worked, and not passed by. Satan will try to interpose himself, so as to discourage the workers, and prevent them from giving the message of light and warning in the more important as well as in the more secluded places. Desperate efforts will be made to turn the people from the truth of God to falsehood. Angels of heaven are commissioned to work with the efforts of God's appointed messengers. The preachers of the truth must encourage faith and hope, as did Christ, your living head. Keep humble and contrite in heart before God. Maintain an unwavering faith in the promises of God.—Manuscript 1, 1874 (similar to Testimonies For The Church 7:34, 35). MTC 5.1
