I wonder if much of what we refer to as "teaching" in today's church doesn't actually fall more in the category of "encouraging" or "exhortation."
This came back to my mind last Sunday when I heard a particularly good sermon on the nature of God. Usually I hear sermons telling me to be a better parent, spouse, or citizen, or how to be more fulfilled, or that we shouldn't be discouraged or we should avoid this or that sin. Sort of the "news you can use" approach to preaching. And all good stuff, but though there is certainly overlap, I think I would categorize it more as encouragement.
It's not that I'm down on encouragement - it's good and necessary - I just wonder if sometimes we forget about teaching. I think of Paul's letter to the Romans. The first 11 chapters are mostly about the intellectual underpinnings of our salvation, then in chapter 12 Paul switches gears and starts talking about how it all applies. I wish more sermons were like Romans - good solid truth followed by good solid application.
Perhaps some people believe truth that is too distant won't have an effect on our lives. But I'm not too sure. When I hear a sermon on the grandeur and mystery and love and mercy and power and justice of our God, I leave with a deep sense of fulfillment, and, I think, am much more amenable to living the way God wants me to live. I want to draw near to God, not just to hear what I should do, important though that is, but to know him better.
