There are two terms in the scriptures which can be confusing. There is a difference between "the end of the world" and "the end of the earth." The end of the world refers to the destruction of the wicked at the advent of Christ's Second Coming. The end of the earth refers to the literal death of planet earth. This occurs after the Millenium and the short season when Satan is loosed, when the thousand years are ended, and men again begin to deny their God, then will I spare the earth but for a little season; And the end shall come, and the heaven and the earth shall be consumed and pass away, and there shall be a new heaven and a new earth (DC 29:22-23, see also Rev. 21:1, Ether 13:9).
