One of the most helpful books I have read for a long time on personal holiness, and particularly on indwelling sin and how to fight it. Lundgaard claims to have dragged John Owen kicking and screaming into the twentieth century, which will be a great relief to anyone who has ever tried to read the almost impenetrably deep prose of the great English theologian. Not only is this book very readable, it is also very challenging. As I read about the ongoing fight with sin and the tactics it uses I felt as if I myself were the case study under the microscope. I was ashamed at how easily I had given in to the continuing assaults of sin in my life up to now, and galvanised to take the fight to my sin in the future. I suspect that far too many Christians know far too little about the powerful hold sin continues to have on their life - and failing to know their enemy they spectacularly fail to fight it. It is time we educated ourselves about our own deceitful hearts, and got busy fighting them. I wholeheartedly recommend this book as a thoughtful, thoroughly biblical, and highly perceptive call to arms in the fight against the enemy within.
