There are many defaults that could be highlighted.  The fact presenter, exhorter and plodder are just three.  Perhaps you can give yourself another title to underline the tendency you see in your own preaching.  Then prayerfully consider how to push yourself beyond what is comfortable for you, or even what is affirmed by others. 

The fact presenter needs to wrestle diligently with sermonic purpose and audience awareness.  The exhorter needs to purposefully engage with the full range of needs present in their congregation, as well as increase sensitivity to the intention of biblical writers.  The plodding passage guide needs to study not just for phrase-by-phrase understanding, but for a fuller understanding of the flow of thought and emphasis, not to mention creative means by which to structure the message.

Here are a few more ways to stretch yourself beyond default, whatever your default may be: 

• How can you preach so that people will not just know the passage, but also experience it?
• How can the message itself be constructed as a plot to be experienced by the listeners?  As preachers we can easily dissect a biblical plot (narrative) and end up preaching an interesting but lifeless set of parts.  We should let story be story, but more than that, how can we take a didactic sermon and add features of plot to it?
• How can the message maintain tension or intrigue throughout?  This means careful consideration of how each point works within itself, and how they work in relation to each other.
• How can the transitions be worked for maximum effectiveness?  How can they be smooth rather than clunky, clear rather than random?
