Ideal for home-based groups or Sunday school classes, or even as an ongoing program offered quarterly in your church, try the Small Group Challenge as a great way to encourage each other to cross the finish line.
The most effective learning happens when two elements come together: when you're in community, and when your community stays together over time. That's why doing The Bible in 90 DaysTM with a group - whether it's a home-based Bible study, a Sunday school class, or a group of co-workers - is such a transforming experience: you're going through it together, in community, over time.
