Most Christians, even if they read on a regular basis, will pretty much choose books that help them live the Christian life. Books extolling “how to” live the Christian life dominate the landscape of bookstores because that is what the market wants.
There is nothing wrong per se with giving practical suggestions for how to live the Christian life. In his terrific introduction to Puritan theology, J. I. Packer underscores how Puritan preachers gave many applications in their sermons.
Applying the truths of Scripture is critical to being a Christian who is growing. James 1:22-25 makes this crystal clear:
But prove yourselves doers of the word, and not merely hearers who delude themselves. For if anyone is a hearer of the word and not a doer, he is like a man who looks at his natural face in a mirror; for once he has looked at himself and gone away, he has immediately forgotten what kind of person he was. But one who looks intently at the perfect law, the law of liberty, and abides by it, not having become a forgetful hearer but an effectual doer, this man will be blessed in what he does.
The problem occurs when one’s reading is all about application. It is a problem, among other reasons, because we simply assume the author holds to a biblical framework. Sure the author may cite verses here and there, but are they handling Scripture responsibly? It takes biblical and theological discernment to determine whether that is the case.
What are the theological assumptions that the author holds? Those assumptions will inform how the author reads Scripture, and then makes his case for believers to apply his suggestions.
I am always on the lookout for thoughtful introductory books that help Christians think more carefully about their faith.
Gerald McDermott’s The Great Theologians: a Brief Guide is such a book. It covers eleven, perhaps the top eleven, most consequential theologians. The chapters are short, but meaty. The chapters are meaty, but accessible.
If you want to know more about the thinkers that are behind the “practical” books you are reading, McDermott’s book is recommended with gusto!
