Following on from reading Saving Eutychus, I’ve been revisiting the form and content of my preaching to consciously hone and develop my preaching craft.
This post from Michael Kruger is also helpful.
Here’s an intro:
Over the years, I have learned to ask students a key question that can reveal a lot about how they are developing as a preacher.
“What did you leave out?”
Most of the time that I ask that question I am met with a blank stare. Students expect to be asked about the content of the sermon—i.e., what was left in. But, they are not prepared to answer the question about what is left out. And there is a reason for that. Often, very little is left out.
One of the key mistakes of young preachers (and a mistake I still make!) is to take all that they have learned during their sermon prep and to put it in their sermon. Every exegetical observation, every textual nuance, every connection with OT (or the NT), every analogy or illustration, makes it into the final version.

Looking forward to reading “Eutychus”. Yes, preaching isn’t a synonym for teaching the aim is to affect the ‘heart’. Being reminded is helpful. Thanks for these consistently edifying and useful posts.
