How any group leader can impact 1000 people in the next 10 years

The average size Sunday School in America is 10 people. On average, children's groups have a few less, while adult groups will have a few more. In large churches, this number will expand slightly, owing mostly to a few huge classes. But still, the average is about 10.

Imagine that this group of 10 doubled every two years or less. Suppose they did it in every eighteen months. What would happen in ten years? (I owe this insight to Andy Stanley who is betting the farm on doubling groups.)

Keeping a constant state of growth, here what it looks like over ten years:

In graph form, it looks like this:

How do we get a group to double every two years or less? Perhaps a little review is in order. There are five steps to a group doubling every two years or less:

Teach a half-way decent lesson each and every week, nothing less will do. You don't have to be Beth Moore to double a class; it does have to be half-way decent.

Invite every member and every prospect to every fellowship every month. Be obedient to the command of Scripture to, "Offer hospitality without grumbling."

Give Friday nights to Jesus. "Friday night" is a metaphor for an informal time of Diet Coke, Coffee cake, and friends. Invite a few absentees or prospects.

Encourage the group toward ministry. The point is not to do the work of 10 men; it is to get 10 men in the work. This point and the next one are the subject of the newest Double Seminar.

Reproduce your group. Ultimately, it is not about going from 10 to 20 as it is going form one group to two.

Why doesn't it happen more often? Why doesn't it happen all the time? Why doesn't it happen routinely?
