My doubt started when I stopped to think: Why there are so many religions? And why "our" religion has to be the "right one"?
That mindset is false. It is just due to the ignorance of the lesser intelligent believers.

If you look at alot of religions, they all basically say the same thing. The only difference is the name of god and the different metaphors used to explain Him. At least it seems this way to me. (Although I guess I could be wrong. I know very little about different religions.)
