I think I lasted something like 12 days and then gave up. I had an experience that actually made me think of this very inconsistency.
I was at church (I still go to church when I’m back at home, to avoid arguments with my parents), and after the service I was milling about in the foyer and came across my uncle talking to another fellow in the church. They know it’s crazy, but they still believe it anyway. So why aren’t we rushing around to get everything done, continually updating our wills, always making sure that funeral plans are arranged, etc.?

A good book is NT Wright’s “Surprised by Hope” which has a chapter on hell that’s quite interesting.
Also, CS Lewis’ “The Great Divorce” presents a very interesting look at the question.
I’m not going to hold a gun to anyone’s head, and for that matter, I don’t think that approach does any good.
But, I will challenge bad thinking and present new information, and perhaps it may cause someone to reconsider their beliefs.
