Atheists do not believe in god so the question is more for those who believe their God is the one and only.
You have the right to place your faith in whatever you choose. But why should you not consider Hinduism, Islam, Buddhism, Judaism etc as possibly the one and only truth of god??
Given the importance of an eternity in the afterlife, should we at least be willing to try out 5, 15, 30 different religions in our lifetime to be 110% sure we picked the right one?
Usually we adopt the religion of the environment we grew up in or whatever our parents told us to believe. Theres millions of catholics but im guessing not so many in Iraq. Millions of Muslims but not so many in Utah.. you get my point.
If youre born in india, Should You believe in Hinduism?
If your a christian from america and are asked 'Should You Believe in Hinduism?', youre gonna say 'Hell no you shouldnt believe in hinduism, you should believe in Our Savior and Lord Jesus Christ the most Awesome Of All.' (maybe you wont say it like that..)
The problem is, what would a hindu from India say when they ask him 'Should You Believe in Christianity?' what do you think theyre gonna say?? If you were born in India, what would you say?
So many religions that believe their particular belief system is the ONLY true religion, but only one can be correct in that assertion. That means a lot of people are wrong, and its possible you could be too. The odds of you having chosen the one true religion out of thousands of other false religions are very, very slim.
Imagine a round table with about ten people representing ten of the most popular religions around the world and you are there representing your faith. How are you going to convince the others that they are wrong, or how can they convince you you are wrong? Would you listen open heartedly to their reasons? Would they consider yours? How much time would it take to decided a winner?
Why is it so easy to dismiss what millions of others believe to be true while at the same time think they should put faith in your belief system. Just because its yours means it must be true?
Why are you so sure all the other gods are wrong?
