It has always been very strange to me how the Big Three Abrahamic traditions (Christianity, Islam, and Judaism, for those of you who've been living in a cave your entire lives) have such incredible staying power. Even in areas where they compete, it seems as though neither or rather, none of three, can make many gains among followers of their rivals. My question, therefore, is; why? Why are the followers of Abrahamic religions just so dang committed to their faith?
