My brother is a successful minister in an evangelical church. I often pick up ideas and phrases from him – expressions which are common parlance in that particular community. One of the most memorable is: “That’ll preach!” Generally speaking, this means that a story or incident has a particular resonance or immediately understood application to their teachings – that it is, by itself, illustrative of what they are trying to convey. If a pastor says this aloud, you may be sure that they are thinking about how to use that anecdote or story, or deploy it, in a future sermon.
So… What does this have to do with OD&D and FRPs?
Pretty much everything.
