I need a book for my nephew will be 18



Would like some good christian reading (I already got them Battlefield of the Mind for Teens by Joyce Meyer) Reccomendations? Thanks!!Can you recommend some Christian books for teens?
How about

THE WORD OF GOD

best book you can give any one..

enough said..

beware of books, which are at least 100 years old! they are mostly false teachers and deceivers..

name a few..

joyce meyer

billy gram

etc..



they teach that God is a pretty god, and will give only the best and you will be surrounded by pretty flowers, and magical candylands..Can you recommend some Christian books for teens?
How about The Shack by William P. Young?
