New Jersualem. A city to be built in Jackson County, Missouri. The Book of Mormon prophesies the coming forth of the New Jerusalem that “should be built up upon this land” (Ether 13:5). Joseph Smith claimed New Jerusalem would begin with the building of a temple and that the city would become a gathering place for God’s “covenant people” (D&C 42:35-36). Neither the temple prophesied by Smith (D&C 84:1-4) nor the city was ever built. Smith attributed this failure to God’s enemies (D&C 124:51).
