Just a thought I had recently, I suspect some one else has brought this up in the past.
I recall a statement in a post Donna sent in  re. no children seen in hell. It was about 7 Coluimbian Christian youths whom God had given a tour of hell. It is a vey powerfull testemony at this link.

Would part of the agony of the 5 unwise virgins be that their children are gone?. It seems to me the children would not be guilty of their parents carelessnes. I am not so sure about the children of the unsaved, since there will be another 7 years possibly and many would become adults in that time period.
 
The tail end of John Johnsons letter is a good reason why the adult Christians who are careless with their lives will be going through this very difficult time. Though we do not all agree on these things I think it is a very good assesment.
