Church gowth by 2020

I have been enjoying David Olson's book, "The American Church in Crisis." He does give some numbers that cause us to reconsider what we are doing and how we are doing it. He said, "Approximately 55,000 churches will close between 2005 and 2020, while 60,000 new churches will open, producing a net gain of 4,500 churches. However, to keep pace with population growth, a net gain of 48,000 churches will be needed. In those 15 years the American church will fall short of this mark by almost 43,500 congregations." (pg 176)
