In light of our increasingly post-Christian Western contexts, David Gustafson offers a mission-oriented ecclesiology that moves from missional theory to practices of missional engagement. Introducing “God’s human drama” as a way to explain the gospel within God’s redemptive story, he outlines specific ways for pastors and church leaders to shape a “gospeling” culture within their congregations. Gustafson expertly lays the foundations of and approaches to evangelism that are seminal and apt for the church today.
