I want to stress what I think that we (or at least I) need more [than instruction about sacrifice]; the joy and delight in God which meet us in the Psalms, however loosely or closely, in this or that instance, they may be connected with the Temple. This is the living centre of Judaism. These poets knew far less reason than we for loving God. They did not know that He offered them eternal joy; still less that He would die to win it for them. Yet they express a longing for Him, for His mere presence, which comes only to the best Christians or to Christians in their best moments. They long to live all their days in the Temple so that they may constantly see “the fair beauty of the Lord” (Psalm 27,4). Their longing to go up to Jerusalem and “appear before the presence of God” is like a physical thirst (42). From Jerusalem His presence flashes out “in perfect beauty” (50,2). Lacking that encounter with Him, their souls are parched like a waterless countryside (63,2). They crave to be “satisfied with the pleasures” of His house (65,4). Only there can they be at ease, like a bird in the nest (84,3). One day of those “pleasures” is better than a lifetime spent elsewhere (10).
I have rather—though the expression may seem harsh to some—call this the “appetite for God” than the “love of God”. . . . It has all the cheerful spontaneity of a natural, even a physical, desire.
—C. S. Lewis, Reflections on the Psalms, 50-51
