I was struck by this thought in Why Johnny Can't Preach. Gordon is responding to those who have dismissed preaching:
I believe the preaching in many churches is so poorly done that it is not, effectively, preaching...If the patients of a given hospital's surgeons continue to die, we could, I suppose, abandon the scalpel. We might also consider employing it more skillfully.
My challenge...is this: Show me a church where the preaching is good, and the church is still moribund. I've never seen such a church. The moribund churches I've seen have been malpreached to death.
