THEY SHALL NOT SLEEP IN THE DUST. Explaining this glorious day [the Millennium] the Lord has given us the following: [D&C 63:50-52; 101:28-31]. Isaiah also says that the age of man, or the age of a tree, is one hundred years, and adds his testimony as follows: “There shall be no more thence an infant of days, nor an old man that hath not filled his days: for the child shall die an hundred years old; but the sinner being an hundred years old shall be accursed.” (Isaiah 65:20).
