Another way of putting the question is: What criteria do you use to evaluate your community?
If you look at how most churches evaluate, you'll tend to think that it's all about numbers. The more, the merrier. How many "got saved" this year? What was the mean attendance at Sunday? And at Sunday School? How many are involved in the ministry?
I don't believe in numbers to evaluate the success of a community. There are better ways of evaluating the success of a community. A good christian community is a community where relationships are strong, no mater what may go wrong. Where there is an equilibrium of gifting, and a sense of respect and humility for each other gifting. That makes a difference wherever it is. That has connections with the outside world. It is also a community that is generating (or in he process of generating) other similar (not equal) communities (this last thing being the signal of complete maturity in a community).
What we have to question ourselves is: Is our community doing that? If not, is it taking measures to do it? Those are very important questions.
