Message 5, The City of God:

Augustine saw the world as a struggle between two ultimate cities—the city of God and the city of man. Augustine knew that he and his brothers and sisters in Christ were citizens of God’s city. He knew that they were called to walk in a manner worthy of the gospel and to live as lights in a dark world. In this session, Dr. Sproul Jr. describes what it means for Christians to be citizens of heaven even as we live in a world that is often dark and hostile to the light of the gospel.
