And Hells come back to haunt me

[snowtracks]

but as you may know, Christ spend an eternity in hell for each person so they could avoid it.

That doesn't make sense. If he spent an eternity in hell, then he is there now and he always will be. He cannot have spent an eternity for each person, since an eternity is basically forever.

The Bible tells us he was dead for three days and a half. That's not an eternity. And for an eternal being, that amount of time is not even the blink of an eye. And it's remarkably unfair for that same being to condemn others to an eternity of punishment.

God evidently has access to a time plane (or something equivalent) which consist of an infinite number of timelines each of which can be expanded or contracted to control the time rate. He is not usher along the cosmic timeline, nor controlled in anyway by it including it's cause and effect one direction property since He is supra-dimensional to time and space.
'torment' is more correctly translated 'restraint'. the more one demonstrates earthly evil, the more restraint they will have in hell. this is to protect others from those that would unleash their most destructive capabilities. Why are they there? they have demonstrated their desires to want nothing to do with God, so He allows them their wishes but still provide them with protection from the most evil and vile. remember, God is true to his nature, and His nature doesn't allow torment. hell's inhabitants don't like there but they want independence from God even more so God accommodates them. Evidently, God creates spiritual being to live forever. there will be a new heaven and earth (Universe), and it will be sealed off from hell.

Think of an individual timeline for each individual eternity conpressed down to a few hours.
