Some preachers love to alliterate their sermons. Others Parry the Practice with a Particularly Purple Passion. This preacher falls somewhere between these two extremes. I use it sometimes when it seems advantageous but realize that it can quickly become a hindrance if not cautiously applied. It appeals to our innate sense of order.
Human beings are orderly creatures.
Made in the image of an orderly God, we're attracted to things that are organized. Disorder unsettles us. Order brings tranquillity. If done properly, an alliterated sermon conveys symmetry and balance. It may provide a memory aid.
