Following on from the last post I see that TGC has their 4 points of Mars Hill Postmortem, over here: http://www.thegospelcoalition.org/blogs/trevinwax/2014/10/16/the-mars-hill-postmortem/
Their fourth point is roughly the point I was making in a cliff note form. I do encourage you to read their first three points though. But perhaps most poignant in there are these quotes from Tim Keller and John Stott:
Tim Keller describes a “gospel-based ministry” not merely in terms of doctrinal correctness but as being “marked by loving honesty, not spin, image, and flattery.”
Likewise, John Stott writes: The Christian minister should be preoccupied with the people’s spiritual progress and care nothing for his own prestige.
I highly encourage reading the whole thing.
