If by some weird metaphysical fluke there was was an all-powerful and all-loving being, then all of its sentient creations would be rewarded with a heaven of some sort and the concept "hell" wouldn't even be given the slightest thought. A being that actually condemned less powerful beings to an eternity of suffering would not be an all-loving being, nor would it be worthy of worship. It would be the biggest and most cruel fucking bully imaginable, and nothing more.
At least the first part of this view corresponds with what the Sikhs believe, if I understand properly. They say that after we die god, as understood by their faith, forgives all sins because that god is all wise and merciful. Speculation about deities is not my specialty, but if I was asked to draw up a god, I'd go that way.
I've always been baffled by versions of god who can be swayed by nagging and theatrics, play favorites, and need to have various grievances repeatedly called to their attention.
In the words of Amy Farrah Fowler: "I'm baffled by one [a diety] that takes attendance" [in church.]
Personally I find the notion of any sort of diety to be balderdash. But I think the existence of the ancient Greek or a similar style of god to be the one that would be most consistent and compatible with reality: They had power, but it had limitations. They felt the range of human emotions. They were competitive and didn't always share the same goals. (Thus explaining why the universe seems to more like having been designed by a committe than by an omniscient being.)
I believe there are literally no gods, but I don't object to speaking of them if it is understood to be in a poetic sense. I do admire some-- a small number-- of the traits of some religions. For example, I admire the simple life and thrift of the Amish. I admire the reverence for the Earth that runs through Native American beliefs. I admire some of the music of Christian religions. My favorite Christmas song is "Oh Holy Night" which, when done well, never fails to put a lump in my throat.
I believe they're all based on faulty metaphysics, but still have produced some aesthetically-pleasing results at times.
It's interesting how Fred Phelps' death and speculation about his whereabouts or fate makes us ponder and share our beliefs. If you believe God disliked Fred Phelp's enough to condemn him to an eternity of Hell, then you may want to ask if your god is looking a lot like the fag-hating Fred Phelps himself.
