After a while the Gentiles will gather by the thousands to this place, and Salt Lake City will be classed among the wicked cities of the world. A spirit of speculation and extravagance will take possession of the Saints, and the results will be financial bondage.
Persecution comes next and all true Latter-day Saints will be tested to the limit. Many will apostatize and others will be still not knowing what to do. Darkness will cover the earth and gross darkness the minds of the people. The judgments of God will be poured out on the wicked to the extent that our Elders from far and near will be called home, or in other words the gospel will be taken from the Gentiles and later on carried to the Jews.
The western boundary of the State of Missouri will be swept so clean of its inhabitants that as President Young tells us, when you return to that place, there will not be left so much as a yellow dog to wag his tail.
Before that day comes, however, the Saints will be put to a test that will try the integrity of the best of them. The pressure will become so great that the more righteous among them will cry unto the Lord day and night until deliverance comes.
