AND this is the Second Death; THE LAKE OF FIRE.—“This destruction or death is called the Second Death in contradistinction to the First or Adamic death, and not to signify that everything which goes into it dies a second time. For instance, death (the first or Adamic death), and Hades, the grave, are to be cast into it, which work will require the entire Millennium to accomplish it; and in no sense will they ever have been destroyed before. So also the devil, the beast, and the false prophet, will never have been destroyed before.”—H. 58; Rev. 21:8.
20:15. And whosoever [was] SHALL not BE found written in the Book of Life.—The writing, the judging, is still future.
Was cast into the Lake of Fire.—“The Second Death, during the Millennial Age, is a part of the utter destruction which will include every improper, injurious and useless thing. (Isa. 11:9; Psa. 101:5-8.) But the Second Death, the sentence of that individual trial, will be final: it will never be destroyed. We rejoice that there is no danger of this, but that Divine Justice unites with Divine Wisdom, Love and Power, to bring in everlasting righteousness on a permanent basis.”—H. 67; Rev. 19:20; Psa. 50:22.
“A thousand years, earth's coming glory,
'Tis the glad Day so long foretold;
'Tis the bright Morn of Zion's glory
Prophets foresaw in times of old.
“What if the clouds do for a moment
Hide the blue sky where Morn appears?
