The bulletin cover provided by UCC Resources for this morning features a full-page picture of Manhattan pre-9/11 with the words, 'How often should I forgive?' I found it very powerful the first time I saw it, and have thought about it from time to time all week.
Last night I woke myself up with an idea for a sermon illustration (stop looking at me so strangely, it's happened before): what pictures specific to our own lives could appear on that cover with the same question?
After I'd slept another few hours and had some coffee I realized that the lectionary text to which that would be relevant (Matthew 18:21-35) is being read this morning, and I'm not preaching. Curses!
