Now is the opportune time to work the cities; for we must reach the people there. As a people we have been in danger of centering too many important interests in one place. This is not good judgment nor wisdom. An interest is now to be created in the principal cities. Many small centers must be established, rather than a few large centers.... MM 300.1
Let missionaries be laboring two and two in different parts of all our large cities. The workers in each city should frequently meet together for counsel and prayer, that they may have wisdom and grace to work together effectively and harmoniously. Let all be wide-awake to make the most of every advantage. Our people must gird the armor on and establish centers in all the large cities. The agencies of Satan are active in the field, putting forth efforts to confuse the minds of men and to fill them with vain imaginations, that they may not become interested in the truth.... MM 300.2
I have endeavored to arouse our people to labor for the unworked portions of the great missionary field, yet but few seem to respond to the appeals of the Spirit of God. We do not realize the extent to which satanic agencies are at work in these large cities. The work of bringing the message of present truth before the people is becoming more and more difficult. It is essential that new and varied talents unite in the intelligent labor for the people. If the burden of these unworked cities rested upon the hearts of our people as it should, they would arouse to labor as they have not yet done for the souls that are perishing in sin.... MM 300.3
The message that I am bidden to bear to our people at this time is, Work the cities without delay, for time is short. The Lord has kept this work before us for the last twenty years or more. A little has been done in a few places, but much more might be done. I am carrying a burden day and night, because so little is being accomplished to warn the inhabitants of our great centers of population of the judgments that will fall upon the transgressors of God's law.—Letter 168, 1909.
