In sections 59-63 Joseph Smith and other leaders arrive at Jackson County Missouri and dedicate a spot where a temple is supposed to be built. The people of the Coleville branch, lead by Joseph Knight travel to Jackson County as the first settlers of Zion the new Jerusalem. History tell us that things did not go well in Jackson county. The saints are persecuted and the temple is never built. Finally the saints are driven out and threatened with extermination by Governor Boggs.
So the question is, why did the Lord lead them to Jackson County is the first place? Didn't he know what would happen there? Why did he ask them to build a temple, when he knew they would be unable? Finally, is Jackson County still chosen to be the place where the New Jerusalem will be built in some future date?
Of course, we don't have answers to these questions. The in some revelations in the Doctrine and Covenants, the Lord said that Zion was not built because of the disobedience of the saints. (D&C103:4) In that revelation the Lord promises that Zion might yet be restored "after your tribulations" (v. 13) The church leaders form "Zion's Camp" to march to Missouri and escort the saints back to their lands. But when they arrive it is too late. All the members have fled. In Section 105 the Lord says "Therefore, in consequence of the transgressions of my people, it is expedient in me that mine elders should wait a little season for the redemption of Zion." (v 9) We know from other scriptures that "a little season" to the Lord can be a long time for we who are mortals. These scriptures make us believe that eventually, Jackson County will be redeemed, and Zion, the New Jerusalem, will eventually be built on that site.
Later, after the saints have been driven from Missouri, and Joseph Smith has languished in Liberty Jail, the Lord rescinds the injunction to build a temple in Jackson County, "Therefore, for this cause I have accepted the offerings of those whom I commanded to build up a city and the house unto my name in Jackson county Missouri, and were hindered by their enemies, saith the Lord your God," (124: 50.) Instead they are commanded to build a temple in Nauvoo (v. 55) which they do. Some would argue that this verse removes the necessity of ever building Zion in Missouri.
Church history buffs are split as to whether they think that Zion will eventually be built in Missouri, perhaps during the millennium. Others say that section 124 nullifies the prophecies about building Zion in Jackson County. I looked online and the church still owns land in Jackson County, but only about 15 acers near the temple lot. They used to own more, but recently sold it off because residents complained that the church held all that land but didn't have to pay taxes on it. The church is certainly wealthy enough, that if they decided to, they could buy up much of the county any time they decided to. However, it doesn't really seem to me that they are currently planning to transfer the center of the church to Missouri any time soon, and I, due to section 124, I am OK with the idea that they probably never will.
