In his work Diffusion of Innovations, Everett Rogers suggests that if 16 percent of a defined constituency adopts a new way of doing things, it creates a movement (262). The odds are in favor of the innovation--that in time upwards to 86 percents of the total population will adopt this new way of thinking and living. I don't know of any suburban church that has reached 17 percent of its households loctated within its area. My thoughts: is this the breakpoint for revival? Another quote from later in the book "Polls would suggest that only 16 percent of the people who live around us are truly immoral." (page 180, statistic cited from Gallup and Jones The Saints Among Us page 10).
