A reader of this site recently asked me to explain how I determine whether a book is good and worthy of recommendation or whether it is not. That is a fair question and I was surprised to find that I had not addressed it in the past. I will take on that challenge today. It will be helpful to assume that the book in question is meant to address the Christian life, falling under the broad categories of Christian Living or Spiritual Growth or something similar (I would have very different questions to ask of a general market book or of a Christian biography).
Here are five questions, plus a bonus, that I ask myself as I read.
Does It Draw Its Truth from Scripture?
First and foremost, a good book will have a heavy dependency upon Scripture. Whatever truth it seeks to teach will be ultimately drawn from God through the Bible rather than from any kind of human wisdom or experience. In the Bible God gives us the great privilege of seeing the world through his eyes and seeing life from his perspective. Therefore, whatever we teach about living the Christian life ought to depend heavily upon his wisdom.
This is the key difference between Randy Alcorn’s Heaven and Don Piper’s 90 Minutes in Heaven—the first is utterly dependent upon Scripture while the second ignores Scripture in favor of experience. It is the great difference between Kent Hughes’ Disciplines of a Godly Man and John Eldredge’s Wild at Heart—the first teaches manhood from Scripture while the other teaches it from human wisdom and experience. This is not to say that there is absolutely nothing right or good in 90 Minutes in Heaven and Wild at Heart; however, they are innately inferior because they do not consistent lead the reader back to God as he reveals himself in the Bible.
Is It Faithful to the Bible?
Of course not all books that attempt to draw truth from Scripture do it well, so the second criteria is that the books are consistently faithful to Scripture. There are many books that attempt to show what the Bible teaches but do a poor job of it. The authors do not handle the Bible faithfully or they look too narrowly, depending upon isolated verses rather than the grand sweep of Scripture. Consider The Purpose Driven Life, a book that contains a good deal of wisdom but which draws from Scripture haphazardly, and compare it to Sinclair Ferguson’s Taking the Christian Life Seriously. Both are guidebooks to life, but one is far more consistently faithful to Scripture than the other.
Does It Have a Gospel Focus?
Many books written by and for Christians teach how to live the Christian life under law instead of under grace. Instead of teaching true Christian living, they teach law and moralisms. A good book will be dependent upon the joy and freedom of living as those who have been set free from law and will ultimately point people to the death and resurrection of Jesus Christ from which we gain the desire and ability and power to live this Christian life. Stephen Artberburn’s Every Man’s Battle is grounded in morality, not gospel; it may be that following rules may help a man overcome an addiction to lust and pornography, but it is far better to point to the gospel, which is exactly what I attempted to do in Sexual Detox.
