In his essay “Message in the Stars,” the American Presbyterian writer and theologian Frederick Buechner conducts a thought experiment. What if God decided to prove—dramatically, irrefutably and publicly—that God does exist by writing across the night sky. Buechner imagines the heavenly author arranging the stars to read—GOD IS—and the subsequent hope, terror, regret, joy and utter astonishment that such a message would bring. He fantasizes that God would write the message in all the different languages of the world, so that on any given night one might go outside, look up and see, in French, Mandarin or Arabic: GOD IS.
He invites us to envision the sense of relief that would come with the utter certainty that God exists.
