"I would go even further: the truths of Christianity would not stir us as they do, nor would they draw us or hearten us, and they would not be embraced by us with such love and joy, if they contained no mysteries. What makes many a man recoil from the Christian mysteries as from sinister specters is neither the voice of nature nor the inner impulse of the heart nor the yearning for light and truth, but the arrogance of a wanton and overweening pride. When the heart thirsts after truth, when the knowledge of the truth is its purest delight and highest joy, the sublime, the exalted, the extraordinary, the incomprehensible all exercise an especial attraction. A truth that is easily discovered and quickly grasped can neither enchant nor hold. To enchant and hold us it must surprise us by its novelty, it must overpower us with its magnificence; its wealth and profundity must exhibit ever new splendors, ever deeper abysses to the exploring eye. We find but slight stimulation and pleasure in studies whose subject matter is soon exhausted and so leaves nothing further for our wonderment. But how powerfully sciences enthrall us when every glance into them suggests new marvels to divine, and every facet of the object imprisons new and greater splendors.
"The greatest charm in knowledge is astonishment, surprise, wonderment. The less we previously knew of a thing, especially the less we dared hope to learn about it by ourselves and the more we marvel at its existence, the more fortunate we regard ourselves when at length we come to know it. The more exalted an object is, the more its beauty and greatness impress us and the more it compels our admiration, the more even the slightest glance that we dare fix on it captivates us. In a word, the charm of truth is proportionate to its abstruseness and mystery. Must not Christianity, too, be especially valuable and dear to us because of the mysteries it involves? And indeed is it not all the more precious the greater are the mysteries which it harbors within itself? Does not Christianity impress us so powerfully just because it is one vast mystery, because it is the greatest of mysteries, the mystery of God?"
