The group needs non-Christians or it becomes a holy huddle. But the right combination of non-Christians, new Christians, and mature Christians can cause a unique dynamic. The lost can find life. The hurting believers can grasp hope. I believe we're on the cusp of a major revival in the United States.
History shows that many revivals began with a groundswell of prayer among youths.
Like shifting underground plates that cause earthquakes, our kids are poised to lead us into revival. My hunch is not yet, but the pieces are coming together to bring in the harvest. And I believe the cell-group strategy will be at the center of this revival. I know of no other structure in the world that can manage the numbers and produce leaders like the cell model. I know there are some that wonder how in the world junior and senior high schoolers can display or possess enough maturity to lead their peers.
