One may speak of Jesus' social vision with one of his most frequently used phrases: "the kingdom of God." Though the phrase had several nuances of meaning, one was theopolitical. His hearers knew about other kingdoms, especially Herod's and Caesar's. The kingdom of God is what the world would be like if God were king, rather than Herod or Caesar. In such a world, the poor would be fortunate, the mighty put down from their thrones, the rich sent away empty-handed. Domination systems would be replaced by God's domination-free order.
