The marriage of the Lamb will occur in heaven on mount Zion as described in Revelation 19:7-8.¹ After the marriage, the wedding parties will descend to earth for the marriage supper of the Lamb as described in Revelation 19:9.² The marriage supper will be held at the city of New Jerusalem (Zion)³ in Jackson County, Missouri.⁴

To prepare for the marriage supper, members of The Church of Jesus Christ of Latter-day Saints will gather⁵ to construct the most significant portions of New Jerusalem⁶ before the Second Coming.⁷ Construction will commence in earnest at the time of the gathering of saints at Adam-ondi-Ahman⁸ and will then continue during the next 3½ years of the Great Tribulation.⁹

People from the tribe of Ephraim will be the primary builders of the city of Zion in Jackson County.¹⁰ Ephraim is the declared lineage for the vast majority of people who are members of the church today.¹¹ After the gathering at Adam-ondi-Ahman, faithful members of the church will gather¹² to redeem the land of Missouri¹³ and build New Jerusalem as the center place of Zion.¹⁴ This holy city will become an ensign to the nations.¹⁵ The saints will also build a temple¹⁶ and a temple complex that will include at least 24 separate buildings.¹⁷ This temple will become the chief or foremost temple in this dispensation¹⁸ and throughout the millennium.¹⁹
