Not a bad primer on teaching youth. Lambert spends a lot of time giving suggestions on curriculum development (though he never gives much help in what a curriculum for youth should include) and doesn't spend nearly enough time helping leaders understand how to develop effective Bible study. All the pieces are here, but not with much clarity. I was looking forward to his chapter on how Jesus taught. Unfortunately, it includes a lot of ideas, but many of them are extraneous--he doesn't really do much with it. All in all, a helpful read for new leaders of youth, but not deep enough for a long-term tool nor practical enough to be a good training book.
This is very basic. It was well researched for the time. It attempts to paint a "Christian education" picture for youth ministers. It is not bad, but it is limited.
