Faith incorporates the unknown into our everyday life in a living, dynamic, and actual manner. The unknown remains unknown. It is still a mystery, for it cannot cease to be one. The function of faith is not to reduce mystery to rational clarity, but to integrate the unknown and the known together in a living whole, in which we are more and more able to transcend the limitations of our external self.
Hence the function of faith is not only to bring us into contact with the “authority of God” revealing; not only to teach us truths “about God,” but even to reveal to us the unknown in our own selves, in so far as our unknown and undiscovered self actually lives in God, moving and acting only under the direct light of his merciful grace.
This is, to my mind, the crucially important aspect of faith which is too often ignored today. Faith is not just conformity, it is life. It embraces all the realms of life, penetrating into the most mysterious and inaccessible depths not only of our unknown spiritual being but even of God’s own hidden essence and love. Faith, then, is the only way of opening up the true depths of reality, even of our own reality.
