Is hell to harsh? What if you were born into a Hindu, Muslim or any other religion's society, you are probably not going to get that familiar with Christianity. The Bible says that the path to heaven is narrow and only few will find it. I understand that getting to heaven is easy, you just have to believe in Lord Jesus Christ and you shall be saved, but often your upbringing is what religion you are going to follow when you grow up. What if some Christian denominations are wrong, i mean obviously Mormonism and such are, but what if only one from Orthodoxy or Catholicism or Protestantism will go to heaven, then it's even narrower. We were lucky that the West adopted Christianity, otherwise there might be a change we would have been raised as something else.
