Missions Doesn't Stop When the Group Has Been Reached

Jesus gave the Great Commission to his church almost 2,000 years ago. He clearly instructed us to make disciples in every people group, to baptize them, and to teach them to obey everything he has commanded. After all these years, more than half of the world’s people groups remain unreached, representing more than one-third of the world’s population. The challenge to reach every people group as quickly as possible resonates in our hearts and prayers, and reverberates in missions conferences. We must reach the unreached because no one can be saved without the gospel.

But subsequent questions easily divide and distract us in our efforts to obey the Great Commission. What does it mean to reach the unreached? What does a reached group look like? And does a people group need any more missionaries once they are reached? Should I feel guilty or mistaken if I believe God is calling me to a group that some consider reached? Discussions about such questions often become more emotional than missiological.

The definition that missiologists often use to describe the term “unreached” is something along the lines of those ethnolinguistic people groups whose population is less than 2 percent evangelical, or those groups without a sufficiently strong presence of New Testament churches or numbers of Christians who could carry on the work without outside help. This percentage metric was devised by missiologists simply to have a commonly embraced benchmark to assist them in talking about levels of evangelical Christianity in various missions contexts. However, it was quickly adopted more broadly as a useful way of discerning which groups had the least presence of Christianity and therefore priority targets for missionaries. Indeed, some even used it to decide where missionaries should go to serve, and when others should leave ministries and redeploy elsewhere.

Certainly those groups with populations that are less than 2 percent evangelical must hear the gospel, and we should use all haste to reach them. Carl F. H. Henry said that the gospel is only good news if it gets there in time. Sadly, for about 50,000 people in unreached people groups every day, it does not. Read more
