Why Do You Believe in a Higher Power?

What is the reason you believe as you do? Is it because of what you've been taught? Is it an experience or something you witnessed that you can't explain? A Dream? A near death experience? Fear of Dying?

Could it be that we want to believe in something because we're afraid of dying, or is the fact that we're aware of our own mortality actually a gift from our Creator, in order for us to find our purpose in this world?

From my own experience, it's a little of everything. There have been things I can't explain, situations I don't know how I made it through, and a fear of the unknown. It seems the older I get, the more I fear the unknown.
