The Enemy Within: Straight Talk About the Power and Defeat of Sin

“Kris Lundgaard has given us a delightful book. Most books about sin don't take God's holiness very seriously or take my lack of it so seriously I can't deal with the guilt. This book does neither. It is honest, real, and, best of all, hopeful. I’m going to get better and this book is going to help. Read it. You'll be glad.”

“An able defender of the Reformed faith, Kris Lundgaard presents a thorough and well-articulated battle plan for taking up arms against the flesh. Confronting and overcoming sin is a constant struggle for every believer. Here is a must read for all who desire not to wave the white flag and surrender to sin, but to soundly defeat it.”

“A wonderful reconnaissance mission behind enemy lines, well describing the spiritual forces that both attack us and attract us by invading our own hearts. Lundgaard forearms us against these assaults by reminding us of how vulnerable we can be when we convince ourselves that we are too secure to fall. Here is a solid reminder that apart from the grace of God we are far weaker than we an imagine—but greater is he that is in us than he that is in the world.”

“Kris Lundgaard has done the impossible. He has given us some of the best of Puritan theology in a language all of us can understand. But watch out. His penetrating style as he exposes sin's deceit will challenge you to radical spiritual transformation! What a wonderful experience to read such a fine author. We can only hope he will give us more.”

“The one area of Biblical teaching that we all tend to minimize is the doctrine of indwelling sin. This book will cure you of that problem, but not in a way that will leave you hopeless and discouraged. The Enemy Within is as honest as anything you will ever read about the power of sin, yet it is infused with the hope of the Gospel.”

“John Owen’s treatises on Indwelling Sin in Believers and The Mortification of Sin are, in my opinion, the most helpful writings on personal holiness ever written. Yet his ponderous, seventeenth-century style is too much for most of today’s readers. In The Enemy Within, Kris Lundgaard has done a notable job of making Owen's teaching readable once again. This is not a twentieth-century revision of Owen, but a fresh, contemporary, highly readable book written in Lundgaard's own style, yet remarkably true to Owen's teaching. Every Christian who is serious about holiness should read this book.”

“The great but cumbersome Puritan John Owen has long been helping Christians to detect indwelling sin, a.k.a. the flesh, in themselves and to overcome it by divine power. Kris Lundgaard presents Owen's teaching on the battle with sin—no more, no less—unshelled and up-dated for today's readers, with questions to help us take it to heart. This book will surely be a milestone for many, just as the original Owen was for many in the past. I heartily commend what Lundgaard has done.”
