This is a good book in its central thesis of interpreting the Old Testament in light of the Gospel. This is generally a good overview of biblical theology. The kingdom is certainly a prominent theme throughout scripture we must be aware of when looking at smaller portions. His view of the kingdom is not entirely in line with Scripture, though quite consistent with reformed dichotomous covenant theology and the over realized eschatology of amillennialism. It turns as you would expect in certain places. This is still a good resource for seeing Christ in the Old Testament.
