Some of the blogs that I frequent have discovered "Wordles," or word clouds, as a fun--and maybe insightful?--way to analyze sermon texts. I'd emphasize the "fun" part and downplay the insightful part. While it's always prudent to choose your words carefully, the "Wordles" method of reviewing sermons would critique a sermon based merely on word counts (and how some programmer set up the software to display words), not on content, or how those words are put together in an overall message.
Here's an example. For this Sunday's sermon various time constraints and added obligations have led me to "pull one out of the barrel," as they say. So, for giggles, I "wordled" my sermon from Trinity 9 of 2004, which I chose to rework for this Sunday. Here's what it looks like:
So, by all means, enjoy the "Wordle" just for fun, but be cautious of serious sermon reviews via word clouds, that is, mere word counts. After all, words don't stand in isolation; they get put together into a larger whole, and it's that larger content, context, and message that's truly deserving of hearing and analysis.
