You know was Christianity* is?
Christianity is like every other faith that every existed, the gods of which now reside, forgotten, in the graveyard of dead gods. One day, just like the gods of the Aztecs and the Philistines, the Ancient Egyptians and the Armenians, the Hittites, the Chinese and Native Americans, the Intuits, the Phoneticians, the Romans, the Siberians, the god of Christianity will be forgotten. Because Biblegod is just as much an invention of men as the other gods were. All it's beliefs and rituals are just like the beliefs and rituals of ancient man. It's just caught on, it's hanging on.
Don't worry when a Christian fundie tells you if you don't believe with you heart and confess Jesus with your mouth you'll go to hell. You won't. Just like you won't go to Valhalla or the Happy Hunting Ground or cross the Rainbow Bridge to the Isle of Apples** or Omeyocan or Tian or one of the Lokis or anywhere. Like other gods had once, the Christian god has got a hold on the minds of men. Like the other gods, it won't last.
There is no Biblegod, so don't worry about it.
*Before you attack me for not having the guts to attack Islam, well Islam is a spin-off of Christianity, it's a lot younger and unlike Christianity and Judaism hasn't yet matured beyond the childish tantrum stage. Read your history. When Christianity was the same age as Islam, it was crusading and auto-de-fe-ing and killing in the name of belief, with more scope to do so, albeit with less powerful weapons.
**I like that belief. I like it.
