During my recent tour through Michigan teaching the infamous “Lesson 14” of Perspectives(“Pioneer Church Planting”), one of my primary emphases was that in the 21st century, the frontiers of mission are shifting radically.  In the latter part of the 20th century, Ralph Winter (following McGavaran and Townsend) opened the eyes of the Church to the reality of unreached and unengaged people groups.  Frontier missiology was thought of as primarily a discussion of how to get the gospel to unreached peoples who had never heard.  It was critical in those days to de-emphasize geography in order to help mission leaders and practioners realize that the “unfinished task” was about reaching peoples rather than about merely establishing the church in every geo-political country.  As Winter said strongly, “Geography is not as important as peoples.”

Today, frontier missions is still about unreached peoples and this has become the overwhelming majority opinion of the evangelical world.  But Winter had also seemed to believe that understanding what was happening to peoples geographically was key for the fulfillment of the Great Commission.  So, to quote Winter with a bit more context,“Geography is not as important as peoples.  Once that is clear, the question of where they are is a very exciting one.“ (Unreached Peoples: What Are They and Where Are They?, 1984) 

Today, we must ask afresh the geographical question of where are the unreached peoples of the world.  Indeed, it may be more appropriate to ask where they are going.  In a new era of mission history, we see a borderless and wireless world of instant communication, high-speed travel, and ever-accelerating mass migration.  People are on the move like never before.  My friend, Joy Tira, likes to refer to this as a “Human Tidal Wave” which is an image that captures well the magnitude and power of diaspora phenomena.

I have much more to say on this issue.  But today, I would rather you take a look at an excellent post by another friend, Justin Long.   In “Shifts in the Remaining Task”, Justin writes about the traditional understanding of “World A, B, and C” or “evangelized” and “unevangelized” and reflects upon how migration and urbanization totally transforming the mission field in our day.

Here’s an excerpt:

Most World A (unevangelized) individuals are found in heavily World B peoples, cities and countries. And more and more, we are seeing World B provinces and cities in World C countries. This is especially the case because of the movements of diaspora peoples into World C countries. Europe today, according to the Atlas of Global Christianity, is home to 28 million unevangelized individuals. I know some will think the number is far higher. My point is only that the West is not 100% Christian, and there’s plenty of room for work. One can’t say that Europe or America is completely evangelized–only that it is largely evangelized.

Please take careful look at Justin’s entire article.  He has done a great job of  helping us to understand the exciting and complex nature of today’s shifting mission frontiers.  Now consider:

1. Do the mission structures of your church reflect the realities of these shifting frontiers? 

2. Who are the “World A” peoples and the “unreached people groups” that live near you?

3. How do you see the “Human Tidal Wave” powerfully changing the dynamics of your city?
