Everyone has a different Religion and belief system. Everyone beliefs in something different. And That's okay, There are many different religions and many different branches of those religions. Some religions believe in one god some belief in many. Some have a belief that their god/gods have a messanger that will carry out his teachings, like Jesus of the Christian religion and he's not the only one. Some belief that there will be another messiah in the coming of the millenium.
Well, it doesn't matter what we believe, We should all get along and have an open mind. There are thousands of religions in Europe and Africa fighting and killing people who belief in something different. But in most religions there is a rule, thou shall harm none. Now why are millions of people killing each other over religion, cause they think those people that have a different belief disobey they're beliefs, well those people killing other people are disobeying they're religion by killing people. And if everyone has a different beliefs, what happens to the other people under that belief system. I highly do not think that many people would go to hell. Everyone sins. Hello That's the human/animal nature to sin. Sins are basically mistakes that people make.
