Danger of Over-Complicated Sermons

"However, in many circles, especially perhaps in some Reformed churches, we may be in danger of over-complicating sermons. By over-complicating sermons I mean... Too much logic, not enough likes: Just read the Gospels and ask yourself if you are like picture-painting Jesus or philosophical Plato. Yes, we need logic. But we also need 'likes' (e.g. the kingdom of heaven is like...) and stories (e.g. there was a rich man...)" (David Murray, How Sermons Work, 145).
