There are among us those who, without the toil and delay of learning a foreign language, might qualify themselves to proclaim the truth to other nations. In the primitive church, missionaries were miraculously endowed with a knowledge of the languages in which they were called to preach the unsearchable riches of Christ. And if God was willing thus to help His servants then, can we doubt that His blessing will rest upon our efforts to qualify those who naturally possess a knowledge of foreign tongues, and who, with proper encouragement, would bear to their own countrymen the message of truth? We might have had more laborers in foreign missionary fields, had those who entered these fields availed themselves of every talent within their reach.... GW 82.2
It may in some cases be necessary that young men learn foreign languages. This they can do with most success by associating with the people, and at the same time devoting a portion of each day to studying the language. This should be done, however, only as a necessary step preparatory to educating such as are found in the missionary fields themselves, and who, with proper training, can become workers. It is essential that those be urged into the service who can speak in their mother tongue to the people of different nations. GW 82.3
It is a great undertaking for a man of middle age to learn a foreign language; and with all his efforts, it will be next to impossible for him to speak it so readily and correctly as to render him an efficient laborer. We cannot afford to deprive our home missions of the influence of middle-aged and aged ministers, to send them into distant fields to engage in a work for which they are not qualified, and to which no amount of training will enable them to adapt themselves. The men thus sent out leave vacancies which inexperienced laborers cannot supply. GW 83.1
