Dr. J's bible study books are written for "children" according to the email reply I got back from Turning Point ministries. I would recommend it for children or newbies. What I do not like is that there is no indication of age group. That would be helpful. I also dislike the excessive use of cliche and old standby religious phrasing. I would recommend instead anything by John MacArthur, Norm Geisler or Michael Youseff. The church has become shallow and routine. It's becoming harder to find good Christian teachers.
