And I saw a great white throne, and I saw the one who was sitting on it.  The earth and sky fled from His presence, but they found no place to hide.  I saw the dead, both great and small, standing before God’s throne.  And the books were opened, including the Book of Life.  And the dead were judged according to the things written in the books, according to what they had done.  The sea gave up the dead in it, and death and the grave gave up the dead in them.  They were all judged according to their deeds.

And death and the grave were thrown into the Lake of Fire.  This is the second death - the Lake of Fire.  And anyone whose name was not found recorded in the Book of Life was thrown into the Lake of Fire.
Revelation 20:11-15
