There are hundreds of thousands of christian books and everyone is always recommending I buy a new one. The problem is that one can read so many books and rarely read the Bible, and or have so many books they do not comprehend the CONTENT of the books. Certain books outside the Bible I believe are vital for all believers and yes every christian needs them. Books like The Way of the Master, Radical, and the Gospel According to Jesus are just a few. How do you practice discernment on the books you read? Some books are very obvious that they are not Biblical and to be avoided. Books such as "Heaven is For Real" "Your Best life Know" "The Purpose Driven Life" "Quitter" or anything by Brian Mclarren, Rob Bell, and just about anything from Charismatic authors and such, however others can be harder to discern, especially if the author is unknown. Do you only read books that your church recommends? Thats the strategy of some and it may be a good one, in order to practice discernment.
