Article of Faith 1:10
10 We believe in the literal gathering of Israel and in the restoration of the Ten Tribes; that Zion (the New Jerusalem) will be built upon the American continent; that Christ will reign personally upon the earth; and, that the earth will be renewed and receive its paradisiacal glory.

Elder Russell M Nelson, “Thus Shall My Church Be Called”, April 1990 General Conference
"It is true that scriptures foretell the final days of the earth’s temporal existence as a telestial sphere. The earth will then be renewed and receive its paradisiacal, or terrestrial, glory. (See A of F 1:10.) Ultimately, the earth will become celestialized. (See Rev. 21:1; D&C 77:1; D&C 88:25–26.) But its last days must be preceded by its latter days!"
