To my bible believing Christian friends I say beware, and be wary about books recommended to you by well intentioned Christian friends or even some Pastors. In fact, best stay away from the latest popular authors and invest your time, energy and money (though some are free downloads) on classics by Tozer, Spurgeon, C.S. Lewis, D.L. Moody and others of their generations. The older the better. Nothing is wrong with reading just the bible. God is faithful to teach you about who He is from His own word.
