That's not how I understood the article at all. I think that the author is looking at the focus of the church (on increasing numbers vs faithfulness to the Word), not at the results of that focus (as God grows these "faithful churches" and not man). I would have described the difference as being between preaching Scripture and developing a marketing strategy. One relies on pragmatic methods while the other tries to be obedient (regardless of "church growth.")
There are comments that make me lean towards the conclusion that the author is speaking of motivation and not size of a church:
“These churches are typically (but not always) small, and, as far as the world is concerned, they usually lack in influence.”
"Our joy doesn’t rise and fall from the ebb and flow of earthly success. Our lives are enriched and full of identity and meaning when we reject pragmatism and simply seek to know, obey, and proclaim His Word."
"Like most of you reading, I have found little success at times when I’m working for it the hardest; and I’ve stumbled into great success when I’ve done absolutely nothing."
I attend a very pragmatic church and have often thought of leaving. Church (for me and my family) is in the small group setting and not the weekly show. So my understanding of the article may be colored by my own experience.
