OP here. Thanks for the responses.
I am in my mid-30s, college educated and well educated about world religions. I took courses in college, have friends of many religions and different faiths, and have felt (as an adult) that it is so important to be knowledgable about other religions - particularly if one professes to be devout in a faith. I was raised in a religious home and feel ties to that faith.
However, over the years of getting to know my in-laws' differing views about this concept, I am beginning to question my own incessant need to be knowledgable about other faiths. My in-laws are not educated, are blue collar, small-minded, and fairly uninterested in the world outside their neighborhood (qualities not in their favor). They are devout in their faith and although they are self-proclaimed ingorami about other world religions, I am beginning to wonder if that actually matters... and here's why: while it is important to be knowledgable about the world, history, culture, etc. for many reasons, I wonder if it is different for religion/faith. Faith is about belief, not about proof, right? So what does it matter what other cultures and people believe, if you truly believe in your faith?
Obviously, faith transcends class and economy - my in-laws' church is composed of rich and poor, educated and not - but getting back to my original point, what does your education matter, if you truly believe in a religion?
I can't decide if I have come to this new viewpoint as a consolation to them, or an educated view that with all of the knowledge in the world, we still believe at heart what we believe?
It has always struck me as interesting that people often go through stages in their lives with their religion - young adults do a lot of soul searching, go to college and learn so much about the world, only to often come back to their heritage (or another faith) in later years of life.
If you are getting my thought process, even if you disagree, let me know your thoughts.
