Or I could be way off and it's just metaphorical. As a spirit, being surrounded by fire and other evil entities would be most unpleasant, but after the resurrection, if a being found itself trapped there, the pain would last for as long as the earth lasts and possibly forever in some way.
As to heaven, I think it might be another dimension. Jesus ascended while witnesses could see him then disappeared in a cloud. The cloud *may* have been the door to another dimension or represent a mystery or concealment.
It seems reasonable that if heaven were someplace in the universe, Jesus would have kept rising until the witnesses could no longer see Him or headed in a different direction other than straight up which is relative to where they were standing and time of day. He ascended of his own power whereas Elijah was shown ascending in a chariot but I don't know if there's anything else about that.
The cloud could represent a mystery or hidden but must have looked real. There are other examples of clouds in the bible but I can't think of the context.
Maybe I should have kept my thoughts to myself because I'm no theologian for sure.
I am glad you shared your thoughts. I am encouraged to conduct futher study on the subject. Thanks for sharing.
Just some of my stranger thoughts. :O)
