I disagree, people describe God very differently. The father-like, interactive God in the Bible is very different from the legalistic God in the Qur'an. How about questions like, "Why do we grow old and die?" "What is sin?" "Do evil-doers burn eternally?", "Why does God allow suffering?" "What does God expect of us?" "Is there life after death?" There are as many answers to these questions as there are religions, but only one reality. These are questions whose answers have immense implications on our lives. What water are you going to drink? The real? The placebo? There's even some straight-out poison out there!!
If you equate the keeping of order in society to the drinking of water - i.e. all religions preach love and peace, and are therefore equal in spiritual value, I again have to object. All religions are either false, or one is true and all others false. They cannot all be true, as some are on a direct collision course with each other and are mutually exclusive. From that follows that humans, to a large extent, invent gods and myths, among other reasons, to keep order in society. Possibly a noble motive, but I think humans should do better than that! Such practices are obsolete in a world in which information and philosophical thought - one of the pre-requisites of morality, are so accessible. We can keep order without lies - just by sticking to principals we know to be true.
I would almost sound like an atheist by saying the above, if it weren't for the fact that complexity, design, what I interpret to be fulfilled prophecy and personal experiences drive me to believe in a God. Now, if I accept the existence of a God, and the pen, which is said to be mightier than the sword, is a tool too powerful to be ignored by our Designer, I find it unlikely that such a potential source of information as literature - the written word, should not be used by Him to convey ideas, set things straight, teach, remind, change hearts and minds over the generations of humans inhabiting this our home.
I would, therefore, without being vain of conceited, consider myself unevenly yoked with someone who is not in search for answers, whose inquisitiveness is insufficient to allow him to reach even the most likely answer to some of the above. I will feel like a horse pulling hard, striving to improve my awareness, judgment, fight selfish traits, adapt a giving mentality, become more people-conscious, etc, while the donkey next to me barely realizes there is a load to be pulled. This is about more than just religion, which may be little more than something written in our passports; it's about spirituality.
