John Owen’s Puritan classic The Mortification of Sin is now accessible to today’s readers in this translation and adaption of his original 1656 English text into our modern English. Owen expertly explains how to put to death sin through faith in Jesus Christ. He tells us why it is important for the Christian to be killing sin in his life, what it means to kill sin, and why only a Christian can do it. He shows why sin can only be put to death by the power of the Holy Spirit exclusively available through the gospel of Christ. “Be killing your sin or your sin will be killing you.” Each of us is in a life or death battle with sin. It’s a battle that can’t be won by willpower or works, but only by the power of the Holy Spirit, who brings the cross of Christ into our hearts with all its sin-killing power. While we will never be completely free of the power of indwelling sin in this world, The Mortification of Sin gives all of us a roadmap to the victory over sin available to us in the gospel of Christ.
