“The Zion of God, or the place where the city of the New Jerusalem shall be built, which shall be the first of the cities of Zion, shall, therefore, be established in Jackson County, Missouri.” (Alvin R. Dyer, BYU Speeches of the Year, Feb. 7, 1967, p. 7)
“What then is the power of the Book of Mormon? It will build the New Jerusalem; it will prepare a people for the Second Coming; it will usher in the Millenium—at least it will play such an important part in all of these that its value and power can be scarcely overstated.” (Bruce R. McConkie, The Millennial Messiah, p. 171)
