According to the author, none of the usual reasons for planting a church is sufficient in itself: obedience to the Great Commission; conducting evangelism more effectively; communicating more relevantly; conducting research and development in new church styles; establishing bases to reach more people; reaching future generations; and impacting existing churches. The only real reason worth starting a church is to achieve transformation in the lives of people and communities. So the dreaming should start not with the church, but with the people outside the church.
Chapter 8 encourages us to start with the society, not the church, and to think like a community developer. We need to know what is going on in the society in the domains of economics, agriculture, education, medicine/science/technology, communication, arts/entertainment, governance/justice and family. Churches emerge when the gospel intersects these domains and people begin to follow Christ.
