The Kingdom of God in Kings and Chronicles

What's amazing about 2 Chronicles 13 is not that Rehoboam's son Abijah claims that Judah is the Kingdom of God. What's amazing is that God backs him up! The whole narrative indicates that Abijah's claim is literally true, that OT Judah under the Davidic dynasty was in some sense the incarnation of the Kingdom of God. To understand this, in turn, gives us the key we need to unlock the book of Kings -- and tells us how imperative it is that we submit to the rule of David's great Son, Jesus Christ.
