The other issue is that these folks will be living with the knowledge they refused Christ and they are there forever by their own choices. They can’t get a do-over. That’s going to be something extremely hard to live with forever. They will beg and wish for one and will be unable to get one. They will be stuck there and they will remember why, forever.
Interesting thoughts! The analogy I always imagine is that God lives in a big house in heaven. If you don’t even acknowledge He exists then you have no business being a guest in his home and are cast in outer darkness. Beyond that I can’t even imagine any of it. I don’t think we are supposed to understand it right now. We should focus on having a relationship with Christ so He knows who we are and we end up in the big house.
The other thing I think about is this thought — everyone gets what they want. Christians get to be with God. Atheists don’t want to be with God and thus they do not spend eternity with Him. Everyone gets what they want!
