There is sometimes lack of understanding, though there may be love, or lack of love through lack of understanding; there may be both things and lack of power. If love has reached perfection it will attain all three powers; when love becomes power, it becomes understanding. The nature of love is as the nature of water in the depths of the earth. If one does not dig deep enough one finds sand, not water; but when one digs deep enough one finds water. Many lovers of God lose patience, trust and hope; they have touched sand and not reached water, but when they have dug deep enough they find pure water.
