Have you ever read the story of Mohammed? It certainly has some similarities to the Joseph Smith story (i.e. visitations, revelation of scripture, etc.). Assuming that people have prayed to God and felt they got an answer that Islam (or any other religion) is "true" -- in much the same way that you have perhaps experienced yourself in Mormonism -- how do you "know" that your "truth" overrides theirs? Why is yours or mine "better?"
Do you believe that Mohammed and the Koran were inspired by God? Why or why not?
Do you believe that God talks to the Pope in the same way that he does to Thomas S. Monson? Why or why not?
Do you believe that the Blessed Virgin appeared to the children of Fatima, Portugal? Why or why not?
Do you believe that God would intentionally direct someone to Hinduism or Judaism instead of Christianity? Why or why not?
I know that most Mormons will say that all religions have some "good" and "truth" to them. But if you haven't studied the other religions of the world and walked in the shoes of someone who practices another faith, how can you "know" that yours is the "only" true religion -- either intellectually or spiritually? What if someone of another faith told you that he had been told by God that his faith was the only true one? On what grounds do we reject the faith claims of others?
I'm curious as to why we all believe the things that we do, why we reject the things that we do, and I'd like to hear your perspectives.
