Revelation20:And the devil, who deceived them, was thrown into the lake of burning sulfur, where the beast and the false prophet had been thrown. They will be tormented day and night for ever and ever.
Then I saw a great white throne and him who was seated on it. The earth and the heavens fled from his presence, and there was no place for them. 12 And I saw the dead, great and small, standing before the throne, and books were opened. Another book was opened, which is the book of life.
The dead were judged according to what they had done as recorded in the books. 13 The sea gave up the dead that were in it, and death and Hades gave up the dead that were in them, and each person was judged according to what they had done. 14 Then death and Hades were thrown into the lake of fire. The lake of fire is the second death.
15 Anyone whose name was not found written in the book of life was thrown into the lake of fire.”
The Bible says that Satan, will be thrown into the Lake of Fire where he is tormented forever. Death and Hell after giving up their dead is also thrown into the Lake of Fire. So are those whose names aren’t found in the Lamb’s Book of Life. There is nothing that says human persons who are thus cast have their souls and spiritual selves dissolved into non existence. Other scriptures speak of the damned as having bodies “fitted for eternal destruction”, “their worm dying not”.
That is inconsistent with the Theme of the whole Bible that God is Love.
A good study on the subject (Kinda long and in depth, though): http://www.biblicalperspectives.com/books/immortality_resurrection/6.htm
