is summed up in this quote by John Maxwell, evangelical leadership and church growth guru:

“When churches run out of new ideas or new programs, they stop growing.”
 
(If that quote piques your interest, be sure to check out some of Maxwell’s books:
Be All You Can Be
The 21 Irrefutable Laws of Leadership
Becoming a Person of Influence
Dare to Dream… Then Do It
Go for Gold
Make Today Count
 
and of course… The Maxwell Leadership Bible: Developing Leaders for the Word of God)
