What do you really know about hell?
How are hell and Hades different? What is the "bottomless pit" and where is it located? Why is "paradise" not the same as "heaven"? Why is the devil in heaven at this time and not hell? Who will be cast first into the "lake of fire"? (Hint: not the devil and his angels.)
For answers to these and other questions, read The Devil's Domain: What the Bible Teaches About Hell.
