Jerry Rankin, president of the SBC's Internation Missions Board, and missiologist Ed Stetzger have teamed up to write a new book called, Spiritual Warfare and Missions. In a recent interview, Rankin laid out the premise of this book:
The whole point [of the book] is not to deal with demon possession, territorial spirits and generational bondage, but to recognize the battle within our own heart of lies and how Satan seeks to defeat us and deter us from the missions task.
Rankin goes on to describe some of Satan's strategies in deterring us from the Great Commission:
The strategy that is working is Satan deceiving the church to be ingrown and self-centered, which is characteristic of our churches today. Satan has led us to selectively interpret the scripture to erode the authority of God’s word and therefore lose any impetus for our global evangelism task. The strategy distorts in the minds of believers that the call to missions is only for an elite segment that is called to be missionaries rather than recognizing that it is a mandate to the church and the people of God.
Ironically, I just had a conversation with my twin brother about this very same issue. Mark serves with his wife Maki as missionaries in Japan, and his heart has been burdened recently with the reality of spiritual warfare in reaching the world for Christ. He plans to speak on this issue at various churches (including mine) this summer on his 6 week furlough.
