Few biblical topics are as important as mission. Mission is linked inextricably to humanity's sinfulness and need for redemption, and to God's provision of salvation in the person and work of Jesus Christ. This "good news" of salvation must be made known. The saving mission of Jesus constitutes the foundation for Christian mission, and the Christian gospel is its message. For Andreas Kostenberger and Peter O' Brien, this significant theme has rarely been given its due attention in biblical theology. Motivated by their passion to see God's mission carried out in today's world, they offer a comprehensive study of the theme of mission. They explore the entire sweep of biblical history, including the Old Testament, the second-temple period, and the New Testament. Together, they have written a biblical theology of mission that listens carefully to the biblical texts, and follows the Bible's "story-line" without flattening the diverse emphases of the various biblical books. Here is scholarship that matters: careful and even-handed, yet of transforming significance for all Christians serious about the mission of the church of Jesus Christ.
