On the earth?
On the farthest edge of
the universe?
In a dimension all its
own?
Revelation 19:20 And the
beast was taken, and with him the false prophet
that wrought miracles before him, with which he
deceived them that had received the mark of the
beast, and them that worshipped his image. These
both were cast alive into a lake of fire burning
with brimstone.
