Jesus said that "the gospel of the kingdom" would be preached to all nations before He returns. He taught a great deal about the kingdom of God in His parables, but also described it as a mystery. In this wide-ranging study we wrestle with foundational questions, such as: What is the kingdom? Is it the same thing as the church (which many have been taught)? Also, has it already come, or should we still be waiting and praying for it?
