Brigham teaches the United States is a land of promise.
Brigham Young, Speech, June 3, 1860, in Journal of Discourses, 26 vols. (Liverpool: George Q. Cannon; London: Latter-day Saints' Book Depot, 1861), 8:67
The Lord has led the people carefully along, and dictated according to his pleasure. Brother Heber says we have been going from place to place, until, finally, we have come into these valleys in the mountains. Why? Because we were obliged to. The Lord has had his eye on this spot from the beginning—upon this part of the land of Joseph. Read the history contained in the Book of Mormon, and ask yourselves whether God has ever suffered a king to reign on this land. Will he ever? No. This is the land that was given to Joseph—the son so well beloved by his father Jacob; and no king will ever reign upon it but the King, the Lord. Could that book have been brought forth and published to the world under any other government but the Government of the United States? No. He has governed and controlled the settling of this continent. He led our fathers from Europe to this land, and prepared the way to break the yoke that bound them, and inspired the guaranteed freedom in our Government, though that guarantee is too often disregarded. He could bring forth his work, and has prepared a people to receive and commence his kingdom. Could this be done anywhere else? No. He has known, from the beginning of creation, that this is the land whereon to build this Zion. He knows how to commence his work and how to finish it, and he will finish it where he commenced it.
