Men learn God's manifold wisdom in creation: in the limpet whose fragile shell may be pierced by a tiny insect, yet resists the blow of the mightiest wave; in the eye that is able to adjust itself immediately to the waxing or waning light; in the hand, so marvellously adapted to its myriad purposes, that the study of its manipulating dexterity has before now convinced infidelity of the being of God. But angels learn the manifold wisdom of God by studying the adaptation of his grace to the varied needs of his saints. As students discover the wonderful resources of the surgeon, who passes through the wards of the hospital adapting himself to the need of each sufferer; so do angels and the lofty spirits of heaven learn secrets they had never known, but for the infinite variety of sin and need and sorrow with which God has to deal, and which become so many prisms to break up the white ray of his character into its varied constituent hues.
