The keys to church growth

Of course you preach the gospel prayerfully in the power of the Spirit and leave the results to him.

But you do a whole load of other stuff too. What really matters?

Humanly speaking, what are the few keys to church growth?

Maybe they include:

(1) Church services and events generally have a good positive feel. People are glad they came and would like to come again. It is the kind of thing they feel they could invite others too.

(2) The qualities of love and friendship are impressive and outward looking. There is a really warm welcome and people are invited in to quality relationships.

What else would you include?

I guess its more than really good flyers and posters - though of course we want those too. I seem to remember our Diocisan Mission and Renewal Advisor saying that he normally finds a touching faith in the power of publicity in parishes. We put up a notice, but the church did not grow. Why?
