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. CT 516.1
But the church may inquire whether young men can be entrusted with the grave responsibilities involved in the establishing and superintending of a foreign mission. I answer, God designed that they should be so trained in our colleges and by association in labor with men of experience that they would be prepared for departments of usefulness in this cause. We must manifest confidence in our young men. They should be pioneers in every enterprise involving toil and sacrifice, while the overtaxed servants of Christ should be cherished as counselors, to encourage and bless those who strike the heaviest blows for God. Providence thrust these experienced fathers into trying, responsible positions at an early age, when neither physical nor intellectual powers were fully developed. The magnitude of the trust committed to them aroused their energies, and their active labor in the work aided both physical and mental development. CT 516.2
Young men are wanted. God calls them to missionary fields. Being comparatively free from care and responsibilities, they are more favorably situated to engage in the work than are those who must provide for the training and support of a large family. Furthermore, young men can more readily adapt themselves to new climates and new society, and can better endure inconveniences and hardships. By tact and perseverance they can reach the people where they are. CT 517.1
Strength comes by exercise. All who put to use the ability which God has given them will have increased ability to devote to His service. Those who do nothing in the cause of God will fail to grow in grace and in the knowledge of the truth. A man who would lie down and refuse to exercise his limbs would soon lose all power to use them. Thus the Christian who will not exercise his God-given powers not only fails to grow up into Christ, but he loses the strength which he already had; he becomes a spiritual paralytic. It is those who, with love for God and their fellow men, are striving to help others, that become established, strengthened, settled, in the truth. The true Christian works for God, not from impulse, but from principle; not for a day or a month, but during the entire life.... CT 517.2
The Master calls for gospel workers; who will respond? Not all who enter the army are to be generals, captains, sergeants, or even corporals. Not all have the care and responsibility of leaders. There is hard work of other kinds to be done. Some must dig trenches and build fortifications; some are to stand as sentinels, some to carry messages. While there are but few officers, it requires many soldiers to form the rank and file of the army; yet its success depends upon the fidelity of every soldier. One man's cowardice or treachery may bring disaster upon the entire army.... CT 518.1
He who has appointed “to every man his work” (Mark 13:34) according to his ability, will never let the faithful performance of duty go unrewarded. Every act of loyalty and faith will be crowned with special tokens of God's favor and approbation. To every worker is given the promise, “He that goeth forth and weepeth, bearing precious seed, shall doubtless come again with rejoicing, bringing his sheaves with him.” Psalm 126:6.—Testimonies for the Church 5:390-395.

A familiarity with the languages of the different nations is a help in missionary work. An understanding of the customs of those who lived in Bible times, of the location and time of events, is practical knowledge; for it aids in making clear the figures of the Bible and in bringing out the force of Christ's lessons.
