Knowing the differences is very important now days. Due to the internet, there are many people from all religions who are spreading false teachings due to their ignorance and some with the intention to deceive. If a belief is not supported by the scriptures then it is false. EternalReligion.org has created this unique comparison with verses from the scriptures to support all statements.
The fact is that if people only know of one book, they they will accept it as the truth, even though there are things in the book which are even against the law of the land in which they live (like slavery, looting, rape, murder, injustice, stoning, religion based tax etc..) . When one is given many options, this can free one from ignorance and bondage to narrow minded ideologies which are against his core beliefs and the law of the land.
