I confess the title is something of a joke. I wrote it, however, to make a point. There are over 7 billion people in the world. More than 4 billion are non-believers, of whom, over 2 billion have no access to the Gospel. Getting to ‘closure’ or ‘finishing the task’ can appear to be an almost impossible job. Breaking the task into chunks can make the task more manageable.
The numbers are huge, but the individual people are found in individual population segments: provinces, districts, languages, etc. Many of these are around 100,000 in size. If we use a fairly simple multiplying strategy, eight generations of church planting would be enough to ‘reach’ a population segment by any current definition, and ten generations would thoroughly disciple it.
Let’s do some math:
Assume the world is broken down into 100,000 population segments. Obviously, you can divide any million-person population into ten such chunks. In real life, they aren’t divided that cleanly. There are, for instance, more people in the Dallas-Fort Worth Metroplex (city) where I live than in many states in America. However, once you get down to the ‘district’ level (one below provinces/states), populations are often measured in terms of hundreds of thousands. My ‘city’ within the DFW area is 250,000 or so.
Assume each discipling leader mentors a group of 6 people. This is fairly conservative; of the 900+ movements we track around the world, the average group size is 15. I use six here because in many highly-restricted places, groups will average 5 to 6 due to security issues. These figures should work almost anywhere.
Assume, of the six the discipler is mentoring, three go on to gather groups of 6 themselves. Again, in our experience, this is relatively common. In restricted-access areas with smaller groups, more people become disciplers with their own groups (because they have a higher commitment due to the security issues). In less-restricted areas, 3 out of a group of 15 isn’t uncommon.
Now, wash-rinse-repeat. Each leader of six in turn mentors three who each gather groups of six, and so on.
You’ll get a chart roughly like the following. Many places are seeing growth far faster than this.
