Look down one road and I see McDonalds, Burger King, Jack in the box, Taco Bell, Wendys, and many more. Look down another road and see just as many different churchs. The first road is competing for your money, whats the second road competing for?
FYI. The king james bible, the one everyone in america has, was written in the 1400s by a bunch of politicans of their day. If you directly translate from the bibles original language to english a lot of key words are mistranslated. Heaven simply means space above us. Never implies a happy lil place for the dead. And the word God translates to a plural word, which means "people from the sky" (aliens rule )
the planet as a whole... christianity is not the most believed. Most people just believe what there told. other wise we'd have more christians in china and more buddists here.
my 3 cents
