I hope this is the right place to post this.. I finally understand this parable!
I've always figured no humans would hold out stubbornly enough to "go to the lake of fire". Yet so many use this parable to support the ultra ridiculous and highly illogical idea of 'hell'.
I always chalked this one up to (1) being a parable
of course, and also (2) the Greek tendency for DRAMA and Jesus was playing along. But since coming to tentmaker site and forum, I see it's probably likely humans may well go to the LOF for individual duration.
I still of course hope not very many! But the understanding feels fuller.. more complete.
