I’ve sometimes heard story-stacking called “skyscraper preaching” – one story on top of another. It is a way of filling the time, though not with the substance preaching requires.
Stacking is when a preacher gathers several stories or pictures and offers them in bulk, one after the other in a confined space of sermon time. It might seem like a good idea at the time, but stacking stories is usually counter-productive. Normally this is not intentional. It happens when a preacher falls in love with a number of illustrations and stories and decides to use all of them without much thought as to what kind of impact this might have on the poor listener. Typically, the result for the listener is confusion. Stacked stories tend to blend into one another, blunting the impact of all. If the preacher had been disciplined enough to use just one of these stories, the listener would have been able to focus his or her attention resulting in a far stronger effect. Stories, well told, are rich events. Stories introduce places and people. They describe places and events. A story carries a narrative. It moves a listener from one place to another. When stories are stacked it is just too many moving parts. The listener cannot commit to so many characters or to so much conflict. There is just too much going on. It would be better for the preacher not to have offered any story at all. Pictures, on the other hand, can be stacked effectively. Unlike stories, pictures are static – they do not move. They offer a snapshot of a particular setting or situation. Typically, pictures require a lot less time to describe, which allows for effective stacking. It can be very effective to open or close a sermon with a series of carefully expressed word pictures that offer an array of examples, opportunities, or which simply combine to set the stage for what is yet to come.
