The leading spokesman for sermon-based groups is Larry Osborne. He says,
“By far the most powerful tool for keeping our back door shut and making the church sticky has been our commitment to sermon-based small groups.

If you would like to experiment with sermon-based groups, but don’t have anyone locally that can write lessons for your groups, I’d love to work with you. I write lessons for a living and feel it is my #1 calling. I think I have written more lessons than any human, living or dead. I have close to 300 series of lessons on Amazon.
Each lesson consists of about 20 ready-to-use questions that save teachers time and gets groups talking. Samples are available here.
I also have a massive electronic library of searchable books. If Max Lucado ever mentioned a particular passage, I will find it and provide it for your teachers. (By the way, with custom lessons I can stay away from, or lean into any authors you choose.)
Stephen Cutchins, Pastor of First Baptist North Augusta said about these lessons:
Josh has written sermon-based lessons that go along with my weekly sermons to my congregation. This has provided a new level of alignment between the topics I present from the pulpit and the conversations that happen in our Connection Groups. Our people love it and it is a great complement to our worship services. It is always a joy to work with Josh and I highly recommend him, and his resources, to you.
This is an idea that lends itself to experimentation. Here is what I suggest. Pick one Sunday in the next month and ask your groups to try sermon-based groups for that one Sunday. I will write one lesson for that Sunday. There will be no charge for this lesson.
If your people like this approach, and you would like to use me as your ongoing lesson writer, the cost will be $799 per month. (For a large church, this is likely less than you are paying for literature now.) As a bonus, you get unlimited access to all my existing lessons for all your members.
