The mission of God to "Go, therefore, and make disciples of all nations" (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. But for every success of the adversary, Rankin and Stetzer point to where Satan is also failing, thus encouraging readers to renew their passion to declare God's glory among the nations. By taking up this call to action now, we can be sure that the kingdoms of the world will become kingdoms for the Lord!
