I need your help, I'm looking up verses with the "Second Death" and "Lake of Fire" using Bible gateway, but so far, I've only found where the devil and his minions burn forever in it, not the unsaved.  So I was wondering: will the unsaved burn forever in the lake of fire?  I'm trying to address a question put forth by Karissa.

(Note: I'm using the KJV exclusively for now.)
