We used a book a couple of years ago to teach youth and adults in a forum-type setting that runs twice a year. I believe the title is "Making the Right Choices". The author, I'm certain, is Josh McDowell. Excellent subject matter, easy to teach, and it's relevant for all ages.
It blessed us so much that it God lead us into developing a a guide for men and young boys. We are entering into the final review stage and we hope for publication to begin soon. If you want more info on it, send me a pm.
