" The same understanding of desire blazes in St. Augustine, fanned by his own experience of passionately searching for God. The Christian life itself is “holy desire.” Commenting on the Epistle of John, he writes, That which you desire you do not yet see; but by desiring you become capable of being filled by that which you will see when it comes. For just as in filling a leather bag . . . one stretches the skin . . . and by stretching it becomes capable of more; so God by deferring that for which we long, stretched our desire; as desire increases it stretches the mind, and by stretching, makes it more capable of being filled.28 "
