Tom,
From my perspective I see a lot of ‘Older son’ syndrome in it. It’s just not fair of God to save everyone when I’VE been so good and obedient and been clever enough to come to the truth in this life. Therefore God has to eternally punish the unrepentant dead otherwise MY salvation will be tarnished as a result.
In fact even if Eternal Torment were likely. I doubt that the dark view through the glass would allow of any other decent Christian position than… ‘Well I don’t know for sure… but I really hope that God will save everyone eventually’.
