Some people groups have thriving, evangelizing churches already living among them. Odds are, if you are taking this topic in a local church, your people group falls in this category. We refer to these as reached people groups.
This does not mean that everyone in the people group is a believer. It doesn’t even mean that everyone in the people group has heard the gospel. It simply means that there are disciples and churches within the people group who able to finish the task. It means that lost people in that people group have access to the gospel, whether they have actually heard it or not. Disciples and churches within that people group can evangelize and disciple the people around them better than anyone else, and that responsibility rests on them.
