From Augustine’s “City of God” (22.30)
““The reward [for the Christian]…will be God himself…who gave the promise of himself, the best and greatest of all promises… He will be the goal of all our longings; and we shall see him forever; we shall love him without satiety; we shall praise him without wearying. This will be the duty, the delight, the activity of all, shared by all who share the life of eternity.”” (“City of God” 22.30)
