I agree and this all points to limited omniscience.
It sounds like you're trying to put God on our level.
Either God is omniscient or He isn't. WE are the one's with limited knowledge. Limited omniscience is No omniscience.
God alone knows who His elect are -- He alone knows who will reject His way to get to heaven.
We are told what hell will be like in the future eternity. Lake of fire and brimstone -- that does Not go out. Utter darkness. Lacking God's presence. God is the light of this world -- without Him there is total darkness. There will be nashing of teeth.
In our human experience with fire -- it eventually burns its self out. A person dies in a fire here on earth. Lots of times, inhailing smoke or fumes will kill the person before the actual flames do.
We Do need to realize that the horrible eternal conditions are meant only for satan, the false prophet and the beast. Everyone else Does have God's way to get to a blissful eternity in heaven -- the New Jerusalem.
There is Also satan -- the greatest liar to mankind ever known. He wants all the company he can get to spend his horrible time for eternity With him. So he tells us lies -- like it isn't really all That bad. Or that all our friends that we are partying with will be there, too, and all the Christian's will be gone so there will be no one to 'preach' to us against all the fun we're having. Well -- probably all the friends they've been partying with Will be there -- but in pain, agony, regret. All the 'if-onlies' IF only we'd Listened to the Gospel that we'd laughed at and Accepted it.
And the lie he's telling us Now is that hell won't really be That bad. His Mercy?! He could annihilate?! Annihilate means to wipe out totally. Exist no more. God has shown His Mercy by providing salvation for us. He originally provided mankind with a perfect environment. The Garden of Eden. We couldn't obey one simply rule -- don't eat of that one tree in the entire garden. Adam and Eve listened to satan instead of God. WE messed up -- God provided His way for us to renew our relationship with Him. The earth and everything on it -- people, animals, ground became cursed. But because OF God's mercy - He has provided salvation From eternity in hell and being able TO enjoy the New Jerusalem in the future.
You're comparing 'hell' to a Geneva Convention- type of separation. You DO realize that the Geneva Convention has been ignored by most every country that entered into it in the first place. Prisoners are Supposed to be treated 'fairly' and 'humainly' by their captors. Sometimes POW's have encountered those 'nice conditions' but mostly Not. Some countries have shown exactly how Harsh they can be -- Those countries make prisoner's wish they Were dead / Could die.
Apparently That discussion Does need to be 'rehashed'.
Satan Wants his future eternal destination to be shared by all the people he is presently LYING to. Remember he's the greatest deceiver known to mankind.
People would Like to think that hell won't be Forever for Anyone. That a person Will be caste there, but it will be like our dying in a fire here on earth. Eventually we'll simply cease to exist.
