Growth of a church = people getting saved + people from other churches – people leaving

People will come from other churches, stay for awhile and move on. Also, a lot of people get saved but leave after a bit.

So cancelling them out means that the equation can be simplified down to:
Growth of a church = people getting saved (and staying saved)

So with reaching a community:

• People are in their homes or at the shops.
• Mail-outs will attract some people
• But ultimately it boils down to somebody talking to them and explaining the gospel.
• Once all the people have had the gospel explained to them (regardless of their decision), the community has been reached.

It’s not rocket science.
