1. Do Not Use The Same Ending
One of the most pervasive sermon close problems that many preachers have is the "recycled end." That is when the preacher always ends the sermon in exactly the same way. Perhaps there are a few ways, but the ending is not tailored to the sermon.
Some will have the exact same end with the exact same whoop or quoting the same thing. "There's power in the name of Jesus, There's hope in the name of Jesus...."
Some always have that "He went on the cross...He died for our sins...He rested in the grave...but EEEEAAARRRLLLLYY Sunday Morning he rose..." Some end with the exact same theme like a "relationship with Jesus" call that is not changed at all based on the sermon.
Do not use the same ending in every sermon!
It is very surprising, but many preachers spend little time thinking about the ending at all. We must recognize that our ending is what people will remember when they go home. It is the ending that gives the preacher a chance to drive home the very important points in the sermon.
However, some sermons just stop. They don't end intentionally. Even some preachers who have reputations for being effective have a number of emotionally intensive portions to the sermon, but their sermon does not seem to progress because the preacher has not put together an intentional end.
We all have heard the sermon that goes on and on because the preacher has not decided how to end the sermon. There was one preacher who couldn't decide if he was gonna whoop or not and so the sermon just continued on as the preacher decided what to do. Great preaching is open to the Spirit, but it is also paradoxically intentional about how it starts and how it ends...
Someone said, "like meat, a great sermon makes its own gravy." As preachers we must recognize this. We cannot take gravy from yesterday's meal and try to serve it on today's meat. We can't ignore the gravy all together either. When closing our sermons we must find a fitting close for this particular sermon that is based in this particular sermon. In addition, we must intentionally move the sermon forward in the way that our Spirit led planning has suggested.
