This is a really, really good place to start. The Lord Jesus taught and preached more about the Kingdom of God than any other subject. The Kingdom of God had been established in the heavens since eternity past, yet even God's people, the Jews, had a very incomplete and significantly warped view of God's Kingdom. By the time of Jesus' day, they had apparently taken on the understanding that the Messiah would actually establish a visible, physical Kingdom on earth. (and he will at the second coming, but this future establishment of the Kingdom on earth is out of our purview for the moment.)
