I am enjoying greatly Jeremy Treat’s, The Crucified King: Atonement and Kingdom in Biblical and Systematic Theology (Zondervan)! Treat has done a tremendous job in wedding Biblical Theology and Systematic – or Dogmatic – Theology, or rather, in seeing how the Biblical text yields the fruit of both. In particular, others have demonstrated the Markan use of Isaiah in Mark’s portrayal of Christ as King and the crucified one. But they have not done it to the degree that Treat has, neither have they shown so interdependently how “King” guards the truth of the Cross (Systematics), and that the Cross/atonement – as developed through Redemptive History – is what beautifies the role of the King (Biblical Theology). You can read the thoughts of others on Treat’s work below.
I also am most eager for the arrival of Richard D. Phillips’ commentary on John in the Reformed Expository Commentary series (P&R).
