The time covered by this volume may properly be called the Kirtland period of the Church History, since that city is the chief center of activity. The four years which comprise the period are marked, on the one hand, by rapid doctrinal development, institutional growth, outward enlargement and internal spiritual progress; and, on the other hand, are marked by internal dissensions, abundant manifestations of human weakness and wickedness, resulting in bitterness and apostasy. The period is one in which the Church is manifestly militant, and not always, from surface appearances, triumphant. Yet removed from {XXIII} that period by well nigh three-quarters of a century, one may see now that it was a glorious period, notwithstanding sombre shadows are now and then cast athwart the pathway of the Church's progress. Who can rightly estimate the value of the experiences of that movement for the redemption of Zion, called Zion's Camp? Nothing so completely reveals the worth or worthlessness of human character as expeditions of this description. Men are thrown into such relations with each other that all that is in them, good or bad, comes to the surface. As opportunities in time of war reveal noble or debased natures, so in expeditions such as Zion's Camp the base or exalted phases of human nature are forced to the surface, and are known and read of men. God, it appears was about to choose His foreign ministry, His Especial Witnesses to the world, the Twelve and the Seventy. After the expedition of Zion's Camp He could choose them from among men who had offered their all in sacrifice--even to life itself--for the work's sake. Are not such manifestly fitter witnesses than those who are untried? Will it be argued that to the All-knowing the untried are as well know as the tried, and that God needed no such demonstration of fidelity as was afforded by the expedition of Zion's Camp in order to guide Him in the choice of His Witnesses to the nations of the earth? If so, my answer would be an acquiescence--God needs no such expedition in order to reveal to Him the worthiness of those who shall be His special Witnesses. But what of the world--what of men? Do not they need some such evidence back of those who shall testify of a new dispensation of the Gospel? Will not men have more regard for the testimony of Witnesses who have offered their all in sacrifice for any given work, than for the testimony of witnesses who have made no such sacrifice? Undoubtedly. Not for God's guidance, then, but for the qualification of the Witnesses in the eyes of men was the expedition of Zion's Camp in part conceived and executed. Also that those men who, under God--the Prophet Joseph Smith and the Three Witnesses to the Book of Mormon--were to make choice of especial Witnesses might know whom to select because of actually demonstrated fitness and worthiness.
