On earth it is clear we humans are split into two main groups: the elect and the non-elect or: those predestined to be conformed to the image of HIS Son and those predestined to the lake of fire.
Why do we live together?
Why must the elect suffer under the evil of the non-elect?
In sum, I believe that some of GOD's elect rebelled against HIS call to come out from among HIS eternal enemies, and became sinful, fallen elect who would perish if the judgement was not postponed until they repented of their idolatry of the non-elect and became Holy in HIS sight, ie ready to damn the non-elect also.
That is why we live with HIS eternal enemies: to learn the nature of the suffering that sin causes, to learn the eternal nature of their evil (5000 years and counting...) and that they will/can never repent so they must be removed.
So, essentially this place is for the elect to choose holiness but the reason they so choose (since the love of Christ is not enough to sanctify us) is what they learn about suffering from the non-elect now that they are in a body that can suffer.
Pretty well everything else is ordinary...
The long version has many scriptural supports which make it very lonnnnnnnnnng...available on request!
