In that marvelous vision known as the "Peaceable Kingdom" (which we find in Isaiah 65), there is the image of the wolf and the lamb feeding together. Well, let me tell you a story about that. Back in the days of pre-perestroika Russia ... when hers was a name that made all of us tremble:  the Russians brought an exhibit to the World's Fair that was entitled "World Peace." In it was a large cage. And in the cage were a little lamb and a Russian wolf ... feeding peaceably together. As an exhibit, it was most impressive. And as the fair unfolded, it was spectacularly attended. One day, however, somebody asked the curator the obvious question: "How in the world do you do it?" To which he replied: "Oh, it's really very simple. We replace the lamb every morning."
