I know that there are some preachers that are very against topical sermons. It is expository or nothing. While I’m sympathetic to this, I don’t fully agree.
I think there are times when a topical sermon is needed. Your community might be struggling with mental illness. Perhaps a cult or heretical group has become active in your area. You can address these things.
What Not to Do
One of the reasons why some are against topical sermons is that there is a temptation to write a speech on a certain topic and then go looking for passages that will help support it. You know if you are doing this if you can remove the Bible passages and it still makes sense. Don’t do this.
What to Do
If there is a topic that needs to be addressed, look for a Bible passage that deals with that topic either directly or in principle (there are few Bible passages that deal directly with the internet). Then preach what that passage says. Don’t start with your opinion but with what the passage actually says. You can look at other related passages but try to stick to the one main passage as much as possible.
I believe that if we do this, we can have the best of both worlds. we don’t have to wait until we get to a relevant passage in our chapter by chapter series. But we also are not presenting just our opinions.
How do you preach topical sermons, if you do at all?
