United States is the Promised Land of the Book of Mormon

Elder L. Tom Perry said, 

"The United States is the promised land foretold in the Book of Mormon—a place where divine guidance directed inspired men to create the conditions necessary for the Restoration of the gospel of Jesus Christ. It was the birth of the United States of America that ushered out the Great Apostasy, when the earth was darkened by the absence of prophets and revealed light. It was no coincidence that the lovely morning of the First Vision occurred just a few decades after the establishment of the United States.

The First Vision precipitated a flood of revealed truth. Knowledge was restored about the nature of the Godhead. A new translated scripture gave a second witness and testament of Jesus Christ. The restoration of the priesthood reendowed mankind with the power and authority to act for and on behalf of God in conducting priesthood ordinances and in reestablishing the Church of Jesus Christ on the earth. We are blessed to be members of the restored Church."
