When all the things that you thought were in your control spins OUT of your control, when you desperately flail your arms to try to grasp for someone who can help you out of your dank hole only to find that people just aren't satifying your needs (even if they honestly DO try), when you feel so impossibly alone in your predicament...
Some people choose to rely on themselves to be their own life buoys. But in doing that, i wonder if they can truly be at peace with the world and with themselves.
Some look for answers and solace outside of themselves. Hence the argument that religion is man-made.
Or how about when everything seems fine and dandy and you feel that there's no need to believe in anything. Life is rosy, your difficulties are never too hard to solve. You have family, you have love. You have enough money, you have your friends. You are happy and comfortable. You are satisfied, and life is going your way.
But you do know, that "Life isn't a bed of roses", don't you? And even if it was, roses have thorns. Roses are pretty, but they can inflict pain too.
So what if one day, one aspect of your life does a mega 180 degree sharp turn, or, one day everything, completely everything fails... In your previously led happy life, who or what were you living for?
Or, perhaps life's generally all right, you're mostly at peace with your existence, but there's always this one or a few aspects of your life that you're always feeling inadequate about and often ask, "why?".
A common plea we always hear is, "GOD, PLEASE HELP ME!". Let's assume that this "God" is not the "God that Christians believe in".
Is it from the influence of our external environment that we blurt out the helpline? Or consider: if you would agree that humans are also spiritual as they are physical beings, do you think that perhaps our calling out reflects something that runs a lot deeper.
