Reading the Word is much more valuble. It hits you from a new angle everytime.
“Is there a best selection of one particular book you are suggesting?”
I’d recommend the first two listed below.
An Introduction to Christianity is a good introduction and refresher. I use it in teaching new believers and as a resource.
Beyond the Quiet Time: Practical Evangelical Spirituality is a guided study for daily devotions for mature believers. It requires the bible, a journal and time.
The Intellectual Origins of the European Reformation is heavy reading and one you do not want to sit in front of the fireplace with an accompanying glass of wine. It is a good study if you are interested in that particular area. From what I’ve seen on this forum between the Reformed and the Catholics, it would probably help.
The Twilight of Atheism: The Rise and Fall of Disbelief in the Modern World is a very encouraging book, but again, it helps to be particularly interested in the area of study.
You will enjoy and be challenged by anything written by Dr. McGrath, even his interviews.
