Church Planting (Keller)

I listened to an mp3 by Tim Keller on "Church Planting".  In it he said the following:

The vigorous, continual planting of new congregations is the single most crucial strategy for the numerical growth of the body of Christ in the city, the continual corporate renewal and revival of all the existing churches.  Nothing else, not crusades, not outreach programs, not parachurch ministries, not growing big old fashion mega churches.

Then he listed 4 basic reasons why vigorous church planting is important:

1) want to be true to Biblical mandate
2) true to Great Commission
3) we are committed to renewing existing church of the city
4) church planting is an exercise of Kingdom-mindedness

"Every local church should have a church planting ministry and/or be involved in church planting" - Tim Keller
