I've done the Truth Project and own the videos. I cannot recommend it enough.
First, I completely share the concern some of you posted about Dobson. His immersion in Psychology is very troubling, and I completely disagree with some of his theology.
HOWEVER, please note that while Dobson supports the Truth Project, he had nothing to do with it. It is taught by Dr. Del Tackett, who is an ordained PCA elder. If you do a little research on Dr. Tackett I think you'll find he's a fascinating man with solid theology, and a gifted teacher.
The Truth Project basically compares relativistic world views with God's view and challenges us to examine where secular worldviews have crept into our thinking. The tagline he uses is "Do you really believe that what you believe is really real?". Not that it's extremely indepth stuff. But it does get the average pew warmer outside of their comfort zones and forces us to examine ourselves and what we believe.
