The need for church planting is obvious in regions where no churches exist. Some critics often argue that fewer large churches would be more effective for evangelism and ministry than numerous small churches. But the impact of small churches shouldn't be underestimated. There is a growing statistical evidence that new churches not only grow faster than established churches but also grow more through evangelism.  In this section of the lecture Craig Ott :

- explains how God's mathematics work; 

- presents practical reasons for church planting and supports them with examples and statistics;

- explains why new churches grow faster than established churches; 

- uses a chart to illustrate that every church is going to plateau.
