I think this picture, which Arni Zachariassen shared, is supposed to illustrate the difficulty of choosing between universalism and the sort of particularism that believes that anyone who is not a Christian (however that is defined) goes to hell.
I wonder whether the unattractiveness of both options ought not to provide encouragement to explore other options, such as annihilationism. Surely ceasing to exist would be better than either spending eternity with Hitler, or eternity knowing that people like Gandhi are in hell.
But it is hard to embrace our own mortality – apparently so much so that it drives some people to Intelligent Design! 🙂
