Reaching All Nationalities, Ranks, and Creeds—Christ recognized no distinction of nationality or rank or creed. The scribes and Pharisees desired to make a local and national benefit of the gifts of heaven, and to exclude the rest of God's family in the world. But Christ came to break down every wall of partition. He came to show that His gift of mercy and love is as unconfined as the air, the light, or the showers of rain that refresh the earth.—The Ministry of Healing, 25 (1905). Ev 568.4
Strangers in a Strange Land—In the courts and lanes of the great cities, in the lonely byways of the country, are families and individuals—perhaps strangers in a strange land—who are without church relations, and who, in their loneliness, come to feel that God has forgotten them. They do not understand what they must do to be saved. Many are sunken in sin. Many are in distress. They are pressed with suffering, want, unbelief, despondency. Disease of every type afflicts them, both in body and in soul. They long to find a solace for their troubles, and Satan tempts them to seek it in lusts and pleasures that lead to ruin and death. He is offering them the apples of Sodom, that will turn to ashes upon their lips. They are spending their money for that which is not bread, and their labor for that which satisfieth not.—Christ's Object Lessons, 232, 233 (1900). Ev 569.1
God's Purpose for the Strangers in Our Land—While plans are being carried out to warn the inhabitants of various nations in distant lands, much must be done in behalf of the foreigners who have come to the shores of our own land. The souls in China are no more precious than the souls within the shadow of our doors. God's people are to labor faithfully in distant lands, as His providence may open the way; and they are also to fulfill their duty toward the foreigners of various nationalities in the cities and villages and country districts close by. Ev 569.2
It is well that those in responsibility are now planning wisely to proclaim the third angel's message to the hundreds of thousands of foreigners in America. God desires His servants to do their full duty toward the unwarned millions of the cities, and especially toward those who have come to these cities in our land from the nations of earth. Many of these foreigners are here in the providence of God, that they may have opportunity to hear the truth for this time. Ev 569.3
Great benefits would come to the cause of God in the regions beyond if faithful effort were put forth in behalf of the foreigners in the cities of our homeland. Among these men and women are some who, upon accepting the truth, could soon be fitted to labor for their own people in this country and in other countries. Many might return to the places from which they came, in the hope of winning their friends to the truth. They could search out their kinsfolk and neighbors, and communicate to them a knowledge of the third angel's message.—The Review and Herald, October 29, 1914. Ev 570.1
A Means of Extending the Work to All Nations—God would be pleased to see far more accomplished by His people in the presentation of the truth for this time to the foreigners in America than has been done in the past.... As I have testified for years, if we were quick in discerning the opening providences of God, we should be able to see in the multiplying opportunities to reach many foreigners in America a divinely appointed means of rapidly extending the third angel's message into all the nations of earth. God in His providence has brought men to our very doors and thrust them, as it were, into our arms, that they might learn the truth, and be qualified to do a work we could not do in getting the light before men of other tongues. Ev 570.2
There is a great work before us. The world is to be warned. The truth is to be translated into many languages, that all nations may enjoy its pure, life-giving influence. This work calls for the exercise of all the talents that God has entrusted to our keeping—the pen, the press, the voice, the purse, and the sanctified affections of the soul. Christ has made us ambassadors to make known His salvation to the children of men; and if we are clothed with the righteousness of Christ and are filled with the joy of His indwelling Spirit, we shall not be able to hold our peace.—The Review and Herald, October 29, 1914. Ev 570.3
Within the Shadow of Our Doors—The message must be given to the thousands of foreigners living in these cities in the home field.... Ev 571.1
Who feels heavily burdened to see the message proclaimed in Greater New York and in the many other cities as yet unworked? Not all the means that can be gathered up is to be sent from America to distant lands, while in the home field there exist such providential opportunities to present the truth to millions who have never heard it. Among these millions are the representatives of many nations, many of whom are prepared to receive the message. Much remains to be done within the shadow of our doors—in the cities of California, New York, and many other States.... Ev 571.2
Wake up, wake up, my brethren and sisters, and enter the fields in America that have never been worked. After you have given something for foreign fields, do not think your duty done. There is a work to be done in foreign fields, but there is a work to be done in America that is just as important. In the cities of America there are people of almost every language. These need the light that God has given to His church.—Testimonies For The Church 8:34-36 (1904). Ev 571.3
We rejoice that the efforts put forth by the pioneer workers among foreign nationalities in the United States and Canada have borne a rich harvest of souls.—The Review and Herald, October 29, 1914. Ev 571.4
City Bases for Foreign Work—We drove out to see the newly established Swedish Mission on Oak Street [in Chicago]. There we were shown a building which our Swedish brethren, under the leadership of Elder -----, have recently purchased for the headquarters of their work in Chicago. The building presents a good appearance. In the basement they have a well-equipped vegetarian restaurant. On the first floor there is a pleasant, commodious hall for meetings, comfortably seated for a congregation of about one hundred and fifty, and the two upper stories are rented to lodgers. I was indeed glad to see this evidence of progress in the Swedish work in Chicago. Ev 572.1
There is a great work to be done for the people of all nations in the large cities in America, and such rallying points as this may be a great help in the matter of gaining the attention of the people, and in the training of workers. In every large city of America there are people of different nationalities, who must hear the message for this time. I long to see evidence that the lines of work which the Lord has marked out are being disinterestedly taken up. A work similar to that which is being done in Chicago for the Swedish people should be done in many places.—The Review and Herald, February 9, 1905. Ev 572.2
Publications in Every Language—To give all nations the message of warning—this is to be the object of our efforts....From city to city, and from country to country, they are to carry the publications containing the promise of the Saviour's soon coming. These publications are to be translated into every language; for to all the world the gospel is to be preached.—The Review and Herald, February 9, 1905.
