Check out what Jesse Smith says about Shift:
"However, that is not to say that the book is not valuable - it is, very much so. While I didn't think that the "meat & potatoes" were there, I did think it was a very choice appetizer. I think that passing on this book to your Senior Pastor (or whatever visionary guides your church) would be an excellent way to get them to begin thinking of bringing families together rather than always keeping them apart. I'd even say that going through the book as a church (senior) staff would be a great idea to shift your focus toward equipping parents - I think I may grab a few more copies and suggest that to our staff.
In short: Get it, read it, mark & highlight it, and pass it on to your supervisor along with your ideas of family ministry in your setting. But don't expect to use it as a resource for how to do family ministry or even how to implement Spiritual Milestones in your church"
