This from my Ministerially Speaking blog:
I heard a well-prepared, well-delivered sermon that was intended to conclude with an invitation. As the sermon was finished a sweet spirit was evident in the service and I fully expected to see several people respond. The case had been made and the Spirit of the Lord was at work.
But the preacher wouldn't land the sermon! Instead, we heard one more story followed by yet another application. By the time people were actually given opportunity to respond the moment had faded and the response was meager.
There are two points in the sermon that especially need to be well thought through by the preacher. The first is the first part of the sermon. The other is the closing of the sermon.
I’m not saying that sermons should never include “in flight” direction of the Holy Spirit, even at crucial points (like leading to a call for decisions). However, the preacher needs to be careful to leave the Spirit room to work in the hearts of the listeners and be leery of telling “one more story.”
