Best preaching text on the Old Testament that I own. He gives a brief overview of preaching throughout the centuries (an entire book could be written on that subject), and then gives his hermeneutic. He gives seven different ways to preach Christ from the OT. 1) Redemptive-Historical; 2) Promise-fulfillment; 3) Typology; 4) Analogy; 5) Longitudinal theme; 6) Contrast; 7) New Testament reference. This book has really shaped my preaching and allowed me to preach Christ consistently and intelligently from each passage of Scripture.
