If you are not one of Dr. Mohler's regular listeners, I'd like to recommend the following podcast:
The Briefing: 09-16-2014 (American Congregations, Federal Courts, Obama, Transgender), by Dr. R. Albert Mohler
Dr. Mohler is not suggesting that we try to keep our children from reading books. Far from it. But he points out how books can and are being used in public schools to turn our children away from our Lord Jesus!
