how small changes add up

Marion Wright Edelman is not speaking about the church here. But there's wisdom in this statement.

Remember this when you worry about your congregation. I don't suggest that you worry about your larger church body; you have enough on your plate in concerns for your congregation, though prayers for church bodies are certainly in order. But keep this in mind:

"We must not, in trying to think about how we can make a big difference, ignore the small daily differences we can make which, over time, add up to big differences that we often cannot foresee."
