My vision of hell is to be alone, without God.
It does not demand fire, brimstone, the devil or anything so terrible as all that. I believe that being without God for eternity would make a fiery hell seem like a good thing.
The 107th Psalm well describes it.
"My vision of hell is to be alone, without God."
Actually, there is an excellent scriptural case for the premise that it's the presence of God that MAKES Hell Hell.
It does not demand fire, brimstone, the devil or anything so terrible as all that. I believe that being without God for eternity would make a fiery hell seem like a good thing.
The problem is that God is not personally present in Hell to restrain evil (because it is the place where people go to get away from Him), yet He has promised punishment and/or suffering there will be related to the sinfulness of its residents. How can He restrain evil without doing so personally?
One way would be to surround each person with just enough fire to keep them from attacking others. Periodically, they would lunge at each other, the frequency of their attacks being determined by their unrestrained level of evil. They would experience the flames in direct proportion to their own sinfulness, yet they would be protected from others' evil.
Ultimately, Hell will be populated by those who believe being apart from God is a good thing. Indeed, their frequent experience in the flames will serve to confirm that belief. The gates of Hell will be locked from the inside.
