We love to look at people and judge them on the basis of what we see. We looked at Lance Armstrong and saw a guy who beat cancer and won Tour de France titles. We saw Bill Cosby as a barrier-breaking comedian and father figure.
I don’t know about you, but I find it challenging to preach on non-narrative texts. It’s easy to make a good story from the Gospels or the Old Testament come alive in a sermon. It’s a lot harder to do that with a theological treatise, so I tend to neglect preaching on the epistles.
