No most think it's the most right. When all is placed on the table it seems the most "logical" (n'really), primarily due to the fact that it's around them daily.
I question it daily, became spiritually weak but never turned in any other direction. Personally I find religions which emphasize spiritual enlightment and seek after knowledge quite attractive but I've never really looked outside the church too hard.
Sense of belonging, comfort and purpose.
If your religion strictly emphasizes values,truth, peace, love for your brother etc. then you wouldn't care about the existence of other such religions. When opposing ideas are presented and your faith is based on what is taught within your religion you HAVE to believe that it is TRUE.
Personally I have my doubts about some of what I've been fed which is possibly why I'm lost right now. I will never swallow any idea/concept which cannot be logically proven.
THERE IS ONE TRUTH!!!!
btw, search the forum so you don't end up repeating threads. Like your style though. Forum junkies like myself need people like you.
