THE ANCIENT OF DAYS. Daniel speaks of Adam as the Ancient of Days. In this dispensation the Ancient of Days will sit in the valley of Adam-ondi-Ahman; and the judgment will be set; Christ will come; and the kingdom will be turned over to Christ; and he will be sustained in his calling as King of Kings and Lord of Lords.
(Joseph Fielding Smith, Doctrines of Salvation, 3 vols., edited by Bruce R. McConkie, 1:, p.106)
COMING OF CHRIST AT ADAM-ONDI-AHMAN. Daniel speaks of the coming of Christ, and that day is near at hand. There will be a great gathering in the Valley of Adam-ondi-Ahman; there will be a great council held. The Ancient of Days, who is Adam, will sit. The judgment-not the final judgment-will be held, where the righteous who have held keys will make their reports and deliver up their keys and ministry. Christ will come, and Adam will make his report. At this council Christ will be received and acknowledged as the rightful ruler of the earth. Satan will be replaced. Following this event every government in the world, including the United States, will have to become part of the government of God. Then righteous rule will be established. The earth will be cleansed; the wicked will be destroyed; and the reign of peace will be ushered in.
(Joseph Fielding Smith, Doctrines of Salvation, 3 vols., edited by Bruce R. McConkie, 3:, p.13)
There will be another great gathering of saints at Adam-ondi-Ahman. Once again the Lord will be there, this time to receive from Adam, the Ancient of days, an accounting of his stewardship. This gathering, at which the Lord will be given "dominion, and glory, and a kingdom, that all people, nations, and languages, should serve him," will usher in the millennial reign. Those in attendance will be the righteous of all ages, each of whom in turn will give an accounting of his own stewardship. We suppose it will be those of all ages who shall partake of the sacrament with their risen Lord. (D&C 27:4-14.) As to their number, Daniel's account speaks of ten thousand times ten thousand and of thousands of thousands, which is to say an innumerable host. All these, being present, shall see and worship the Lord. (Dan. 7:9-14.)
(Bruce R. McConkie, The Promised Messiah: The First Coming of Christ, p.610)
With reference to the use of sacramental wine in our day, the Lord said to Joseph Smith: "You shall partake of none except it is made new among you; yea, in this my Father's kingdom which shall be built up on the earth." In so stating, he is picking up the language he used in the upper room. Then he says: "The hour cometh that I will drink of the fruit of the vine with you on the earth." Jesus is going to partake of the sacrament again with his mortal disciples on earth. But it will not be with mortals only. He names others who will be present and who will participate in the sacred ordinance. These include Moroni, Elias, John the Baptist, Elijah, Abraham, Isaac, Jacob, Joseph (who was sold into Egypt), Peter, James, and John, "and also with Michael, or Adam, the father of all, the prince of all, the ancient of days." Each of these is named simply by way of illustration. The grand summation of the whole matter comes in these words: "And also with all those whom my Father hath given me out of the world." (D&C 27:4-14.) The sacrament is to be administered in a future day, on this earth, when the Lord Jesus is present, and when all the righteous of all ages are present. This, of course, will be a part of the grand council at Adam-ondi-Ahman.
Adam-ondi-Ahman-meaning the place or land of God where Adam dwelt-is at a place called Spring Hill, Daviess County, Missouri. This site is named by the Lord "Adam-ondi-Ahman, because, said he, it is the place where Adam shall come to visit his people, or the Ancient of Days shall sit, as spoken of by Daniel the prophet." (D&C 116.) There is a great valley there in which the righteous will assemble; and where there are valleys, the surrounding elevations are called mountains. Thus our revelations speak of "the mountains of Adam-ondi-Ahman" and of "the plains of Olaha Shinehah, or the land where Adam dwelt." (D&C 117:8.) Sacred indeed is the whole region for what has taken place and what will take place in its environs.
Adam-ondi-Ahman, the land of God, the dwelling place of Adam-surely it is a blessed and holy place! There Adam our Prince will give an accounting to Christ our King. The Prince serves the King! The King always is supreme, though he honors the Prince by giving him power and dominion over his realms for an appointed season. But when the King returns, the Prince steps aside, and the Supreme Lord of all rules and reigns on earth. And thus, as the Lord lives, has it been and will it be.
(Bruce R. McConkie, The Millennial Messiah: The Second Coming of the Son of Man, p.587-588)
But Daniel has yet more to say about the great events soon to transpire at Adam-ondi-Ahman. And we need not suppose that all these things shall happen in one single meeting or at one single hour in time. It is proper to hold numerous meetings at a general conference, some for the instruction of leaders, others for edification of all the saints. In some, business is transacted; others are for worship and spiritual refreshment. And so Daniel says: "I saw in the night visions, and, behold, one like the Son of man came with the clouds of heaven, and came to the Ancient of days, and they brought him near before him." Christ comes to Adam, who is sitting in glory. He comes to conform to his own priestal order. He comes to hear the report of Adam for his stewardship. He comes to take back the keys of the earthly kingdom. He comes to be invested with glory and dominion so that he can reign personally upon the earth. As President Joseph Fielding Smith expresses it: "Our Lord will then assume the reigns of government; directions will be given to the Priesthood; and He, whose right it is to rule will be installed officially by the voice of the Priesthood there assembled." (The Way to Perfection, p. 291.) Thus Daniel says: "And there was given him dominion, and glory, and a kingdom, that all people, nations, and languages, should serve him: his dominion is an everlasting dominion, which shall not pass away, and his kingdom that which shall not be destroyed."
Daniel also tells us of the conflict between the kingdoms of this world and the kingdom of God. In spite of the opposition of the world, he says, "the saints of the most High shall take the kingdom, and possess the kingdom for ever, even for ever and ever." And also: "I beheld, and the same horn made war with the saints, and prevailed against them; until the ancient of days came, and judgment was given to the saints of the most High; and the time came that the saints possessed the kingdom." In this present world Lucifer reigns. This is the great day of his power. The kingdoms of men prevail in many ways over the Church and kingdom of God. Evil forces "devour the whole earth, and shall tread it down, and break it in pieces." But Lucifer's day is limited; he shall soon be bound. "The judgment shall sit, and they shall take away his dominion, to consume and to destroy" the Lord's work and his kingdom. "And the kingdom and dominion, and the greatness of the kingdom under the whole heaven, shall be given to the people of the saints of the most High, whose kingdom is an everlasting kingdom, and all dominions shall serve and obey him." (Dan. 7:13-27.)
