I attended a meeting of an astronomy club and the scientific presentation was way over my head. I later called the presenter to get some clarification and he was taken aback that his information came across as deep. I can understand his discomfort. On the religious landscape mature believers would cringe if our presentations were over the heads of our audience. However, it occurs to me that many of the sermons we hear today have shifted to shallow simply because teachers fear talking over the heads of those in the congregation. Jesus proved that a simple message can have depth (parables). However, Jesus also knew his audience — the Pharisees and little children were not taught in the same style, or manner.
