Book excerpt: The mission of God to “Go, therefore, and make disciples of all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Spirit” (Matthew 28:19, HCSB) is a major target of spiritual warfare today. In this new book by International Mission Board president Jerry Rankin and noted missiologist Ed Stetzer, the authors call out Satan’s ongoing strategy to convince Christians that the Great Commission is optional. Through deceit, he is eroding the authoritative mandate of Scripture, leading believers to tell themselves that international discipleship is a task better left to denomination and mission agencies—not the sort of kingdom work that every believer can do. But for every evil success, Rankin and Stetzer point to where Satan is failing, thus encouraging readers to renew their passion to declare God’s glory among the nations. Indeed, by taking up the call to action here, we can be sure that the kingdoms of the world will become the kingdom of the Lord.
