 John, we've highlighted some fascinating research from a good friend of ours, Dr. Cara Powell. She's out at Fuller Theological Seminary. And they found that a startling number of kids drift from the faith, but a number of them do come back over time. But sadly, some don't. Some kids grow up in Sunday school and church and youth group, and they still leave their homes believing Christianity is a list of do's and don'ts, simply behaviors.
