People want Hell.
Not for themselves, or for really nice people who don't believe in a triune G-d. No. Hell is for the people they hate. People who do bad things. Corrupt officials, the guy who cuts you off and gets away with it, jackasses. Hell. People want Hell for those people. If there is a god, his grace would be denied to those wrong doers, or he'd judge them to Hell, or somehow they'd get there without a G-d.
I'm willing to entertain the idea, I heard from my liberal priest (back when going to St. Georges) supposed that G-d's grace is extended to all, and he can save all, and even the worst of us can be welcomed into Heaven by G-d's grace. However, I don't believe there is no one in Hell. I do believe in the human ability to be stubborn into eternity and would deny that he is Lord or reject his love and doom themselves to Hell. Or a Hell.
I have various views of Heaven and Hell. If Heaven is an eternal Mass, or worshipfest of G-d, that would be Hell to someone. The idea of hanging out with Jesus and singing his praises sounds alright to me (I worry about bad worship music, yes, even in Heaven, Praise and Worship Pop music could sneak in).
