I remember Dallas Willard writing in The Spirit of the Disciplines regarding the problem in evangelicalism of "undiscipled disciples". Where does discipleship fit? Is it an addendum after a person "gets saved"? Is it a program or a curriculum?
What Lunde is offering is linking following Jesus to biblical history, particularly the concept of covenants. Frankly, it's an immense project and the fact that he did not cover every aspect is representative of the scope. However, what he covers is essential to recovering a more robust understanding of discipleship, the gospel, and how God is working out redemptive history. I'm realizing that good, solid biblical theology is being done today and Lunde is right in the heart of it all. I think what this offers to the church that often finds itself stuck in technique and trying to be relevant, something that is much more in line with what the church should actually be. His referencing both Christian Smith and David Kinnaman and their assessment of modern Christianity at the end provides the impetus for real change in how we do ministry.
This book fits well with others that are writing about biblical theology and connecting it to a fuller understanding of the gospel - Keller, Chris Wright, Carson, Motyer, and a few others. As a pastor I would say this represents a paradigm shift in how we think about the Bible, the gospel, and ministry. This series (along with New Studies in Biblical Theology) represents a great step in providing an aid to the church to understanding the biblical message as a whole!
