When we are endowed with the Wisdom of the heart, but do not have access to knowledge, we are ignorant. Then we only believe what we see, or what has been proven to our satisfaction. Since it does not occur to us that we may be endowed with supernal wisdom, we do not open ourselves to the mystery of the Spirit that invisibly permeates the created world. So long as we limit our explorations and activities to the visible world as though that were all that existed, we must remain blind to the transcendent beauty of the eternal world.
Prayer and meditation have an important part to play in opening up new ways and new horizons. If your prayer is the expression of a deep and grace-inspired desire for newness of life—and not the mere blind attachment to what has always been familiar and "safe"—God will act in us and to prepare what we cannot yet imagine or understand. In this way our prayer and faith today will be oriented toward the future which we ourselves may never see fully realized on earth.
