Behold, there shall be a record kept among you; and in it thou shalt be called a seer, a translator, a prophet, and an apostle of Jesus Christ, an elder of the church through the will of God the Father, and the grace of your Lord Jesus Christ… Wherefore, meaning the (LDS) Church, Thou shalt give heed unto all his words and commandments which he shall give unto you as he receiveth them, walking in all holiness before me; For his word ye shall receive as if from mine own mouth, in all patience and faith (Doctrine & Covenants 21:1 & 3-4).

This earth, according to the divine plan, is passing through a mortal or temporal existence of seven millenniums or 7000 years. During the first six of these (covering a total period of 6000 years from the time of the fall of Adam) conditions of carnality, corruption, evil, and wickedness of every sort have prevailed upon the earth… When the 7th thousand years commences, however, radical changes will take place both in the earth itself and in the nature and type of existence enjoyed by all forms of life on its face. This will be the long hoped for age of peace when Christ will reign personally upon the earth… This is the period known to the saints of all ages as the Millennium (Mormon Doctrine, p. 492).

In the beginning of the seventh thousand years will the Lord God sanctify the earth, and complete the salvation of man, and judge all things, unto the end of all things; and the sounding of the trumpets of the seven angels are the preparing and finishing of his work, in the beginning of the seventh thousand years—the preparing of the way before the time of his coming (Doctrine & Covenants 77:12).

When the time approaches for Christ to come and reign personally upon the earth for the millennial period, then Adam and all those subordinate to him who have held keys and authority will meet in the Valley of Adam-ondi-Ahman. There an accounting will be made of all stewardships; Christ will come and receive back the keys; and there will be "given him dominion, and glory, and a kingdom that all people, nations, and languages, should serve him" (Dan. 7:14). Following this all will be in readiness for our Lord to reign personally upon the earth, and he will soon thereafter come to usher in the great millennial era (Mormon Doctrine, p. 493).

In accord with the revelations given to the Prophet Joseph Smith, we teach that the Garden of Eden was on the American continent located where the City Zion, or the New Jerusalem, will be built. When Adam and Eve were driven out of the Garden, they eventually dwelt at a place called Adam-ondi-Ahman, situated in what is now Daviess County Missouri (Doctrines of Salvation, vol. III, p. 74).

I will reveal myself from heaven with power and great glory, with all the hosts thereof, and dwell in righteousness with men on the earth a thousand years, and the wicked shall not stand. And again, verily, verily, I say unto you, and it hath gone forth in a firm decree by the will of the Father, that mine apostles, the Twelve which were with me at Jerusalem, shall stand at my right hand at the day of my coming in a pillar of fire, being clothed with robes of righteousness, with crowns upon their heads, in glory even as I am, to judge the whole house of Israel, even as many as have loved me and kept my commandments, and none else (Doctrine & Covenants 29:11-12).

The Church of Jesus Christ of Latter-day Saints is the kingdom of God on earth; it is the kingdom which shall never be destroyed or left to other people; it is the kingdom which shall break in pieces and consume all other kingdoms; and it shall stand forever (Dan. 2:44). But for the present it functions as the ecclesiastical kingdom only. With the millennial advent, the kingdom of God on earth will step forth and exercise political jurisdiction over all the earth as well as ecclesiastical jurisdiction over its own citizens (Mormon Doctrine, p. 499-500).
