The first rule of combat is: know your enemy. We don't talk much about sin these days. But the Puritans sure did--because they understood sin's power and wanted to root it out of their lives. Shouldn't we want the same? Few books on the doctrine of sin are as practical and applicable as this one. Mark Jones puts his expertise in the Puritans to work by distilling the wisdom of our Christian forebears into a single volume that summarizes their thought on this vital subject. The result is a surprisingly relevant book that you'll refer to again and again. None of us is free from the struggle with sin. The question isn't whether we're sinful, it's what we're doing about it. With God, there is a path to overcoming sin. And the first step on that path to victory is knowing what we're up against.
