Found the quote from pg. 33 The Emerging Church
"Contrary to much of our current thinking about the importance of powerful youth ministries to the lifelong spiritual development of future adults, research proves otherwise: a teenager who attends a church's worship service on a regular basis and does not attend youth group is more likely to continue attend church worship services as an adult than a teen who is active in youth group but doesn't attend worship services with other age groups." - Mark Oestreicher
Thoughts? How do you integrate teens in your church?
