Jacob’s understandings of consequences do not sound inherently unpleasant.

To me, isolation and estrangement from the love of God and neighbor seems pretty "unpleasant."    

Why completely reject the supernatural? If we reject the
supernatural, we might as well reject Jesus’ resurrection, and indeed,
our future resurrection.

Why cling to the "supernatural"?  It is not Bibilical. 

And since "supernatural" is not in the Bible, I think it is a stretch to claim that the rejection of the "supernatural" is a rejection of "Jesus’ resurrction, and indeed, our future resurrection." 

Moreover, given the predominance of scientific naturalism, I think that the whole notion that "Jesus’ resurrection" is a "supernatural" event has done great damage  to the compelling story of Jesus’ life, death and resurrection.  

I think that we should get past the supernatural/natural dichotomy that structures and limits our thinking.  I think we would benefit from keeping life on the level of relationships.  We relate to self, neighbor and God.  None of these bonds are "supernatural," I would submit.      

As for my understanding of hell, one word: judgment.

Yet nowhere does Jesus talk about "hell" as "judgement."  Granted, to sit in "judgement" is to relate to someone in a particular way.  But nowhere does Jesus suggest that "hell" is "judgement."  Does he?
