The past few post have been dealing (in one way or another) with the topic of hell. I wrote a few short post where I BRIEFLY touched on some of the subjects dealing directly or indirectly with how one thinks about the nature of hell.
Doug Pagitt, pastor of Solomon's Porch in Minnesota, recently participated in a debate dealing with the topic of hell. He posted the videos on his blog which you can find here.
There are a total of 9 videos so I encourage you to watch what you can and check out the rest of Doug's site while you are there. I recommend buying a book!
