1. Launch a new sermon series. Whether your style is to preach verse-by-verse through a book or to preach topically by subject, no one likes walking into the middle of a sermon series. It would be like walking in an hour into a movie and expecting to keep up with what’s going on. Knowing that your greatest concentration of visitors will be coming in August, time your sermon series to end in July, allowing you to start fresh in August. A new sermon series will make it easier for guests to follow along with the messages and make them more inclined to come back.
