“At present we are on the outside of the world, the wrong side of the door. We discern the freshness and purity of morning, but they do not make us fresh and pure. We cannot mingle with the splendours we see. But all the leaves of the New Testament are rustling with the rumour that it will not always be so. Some day, God willing, we shall get in. When human souls have become as perfect in voluntary odedience as the inanimate creation is in its lifeless obedience, then they will put on its glory, or rather that greater glory of which Nature is only the first sketch.” (C.S. Lewis)
NB: C.S. Lewis was an Anglican, yet many of his insights were profoundly Catholic.
