its not in existence yet. The hell the rich man was at, when you follow it all threw to the end, is a torment of his own making, meaning he could see Abraham, and Lazarus ,that they have that immortal soul, meaning they made it. But his fate was still in question, and cant join in and be apart of all the things he sees there. This is torment to him. When he asked for water, think that Christ is the living water, that when you partake that brings about eternal life. Its truth .
Pual , would say of people wanting to be together in passion, he said its better to marry then to burn. This dose not mean litteral burning., So likewise the rich mans burning in flames, is also used in a figure of speech for his particular situation.
God would not send people to hell, for the short time we have in life, to figure things out.
So the rich man is this paradise, as Christ would put it, or prison as Peter worded it. But, its all heaven, according to scripture overall, because as Ecclesiastes and Christ, Peter, where ever you want to start reading, says to be absent from the Body is present with the Lord . It's not, to be absent from the body, is in hell or in heaven. Scripture is not just that simple, there is more, detail given then that. . It can be a literal divide, or a figure of speech, meaning hes basically an outsider there, until farther notice, like the Lords Day written of in Rev 20.
So there's more here then meets the eye at first glance, until we study with understanding these things. And the actually lake of Fire, where a soul can die, is not even in existence yet. The Bible teaches all this
