ces: kill or be killed. The sin that lurks inside each one of us is cunning, resourceful, and relentless. Much as we'd like to avoid thinking about it, it is a foe we must know, and hate, in order to fight effectively. In this expanded edition of a time-tested classic, Kris Lundgaard provides tactical guidance on how to wield lethal faith against sin in everyday life. Drawing on the wisdom of John Owen's masterwork, The Mortification of Sin, he challenges us to battle for holiness with confidence in Christ's Spirit and victorious work on our behalf. Practical reflection and discussion questions make this book a helpful resource for group study, and a new chapter on the church emphasizes that sin's battle is best fought alongside others.
