A Quaker spiritual classic by Thomas Kelly. How can we be sure that God is real, and not just a creation of our wishes? We have disquieting desires for a God, for a real God. There come to us times of loneliness when we seem to have a premonition of a deep vastness in ourselves, when the universe about us, gigantic as it is in all its starry depths, seems cramped and narrow for our souls, and something makes us long for an abiding Home. We have times of fatigue, of confusion, of exhaustion, of utter discouragement, when we long for a serene and everlasting Bosom on which to lay our heads and be at peace. But how can we be sure that what we call God is not a product of our wishful thinking, a self-delusion we create, a giant shadow of our longings flung up against the sky and asserted to be real?
