How not to preach an expository sermon

"Expositional Imposters" by Mike Gilbart-Smith is a keeper on how not to preach an expository sermon. The essay contains seven points, all worthwhile, but the middle one in particular caught my eye:

Too much preaching promotes pride in the congregation by throwing bricks over the wall towards other people’s greenhouses. Either the point of the passage is applied only to non-believers, suggesting that the Word has nothing to say to the church, or it is applied to problems that are rarely seen in the congregation that is being preached to. Thus the congregation becomes puffed up, and like the Pharisee in Jesus’ parable ends up thankful that they are not like others. The response is not repentance and faith but, "If only Mrs Brown heard this sermon!" or "Umpteenth Baptist Smorgsville, Pennsylvania really ought to have this sermon preached to them!"
