The importance of Biblical Theology to the church ministry is both direct and indirect. Biblical Theology directly helps us do church ministry by enabling us to preach the Biblical theology themes of Scripture and show the unity of the Bible. Edward W. Klink III and Darian R. Lockett make this point in their discussion of the history of redemption: “the major themes and overarching structural ideas (e.g., covenant, a kingdom, and promise and fulfillment).” Our preaching on these great themes also shows our people how to study the Bible.[1] Klink and Lockett call this the “Chicago School” approach of D.A. Carson and his “whole-Bible Biblical Theology.” But the Biblical Theology of the “Dallas School” can aid the preacher’s ministry of preaching through books. The “Dallas School” approach is described by Darrell L. Bock: “Biblical theology is an attempt to study individual contributions of a given writer or a given period to the canons’ message.”[2] This is different from the “whole-Bible Biblical Theology” of D. A. Carson and Trinity Evangelical Divinity School. “The Dallas School” approach is found in two Biblical theologies produced by the faculty of Dallas Theological Seminary: A Biblical Theology of the Old Testament and A Biblical Theology of the New Testament. The second volume includes “A Theology of Matthew”, “A Theology of Mark”, as well as Luke-Acts, John’s Writings, etc. This approach would greatly help preaching a series through one of these books. And, again, this kind of Biblical Theology preaching demonstrates to our people how to study a book of the Bible.
