St. Bernard of Clairvaux
What else is achieved by meditating on such great and so undeserved mercy, such gratuitous and so proved a love, such unexpected condescension, undaunted mildness, and astonishing kindness? ... Then the bride surely runs more eagerly in the odor of [these qualities'] perfumes. She loves ardently, yet even when she finds herself completely in love, she thinks she loves too little because she is loved so much. Nor is she wrong. What can requite so deep a love by so great a lover? It is as if a tiny grain of dust were to gather all its strength to render an equal love to the Divine Majesty who anticipates its affection and is seen entirely bent on saving it.
--St. Bernard of Clairvaux, On Loving God
