Romans Romans 8:12-13


In Romans 8:12–13, Paul reminds believers that we are no longer under obligation to the flesh, but are called to put to death the practices of the body by the power of the Holy Spirit. In this sermon, “Be Killing Sin or It Will Be Killing You,” we examine the biblical doctrine of mortification through the life and ministry of John Owen, the “Prince of the Puritans.”

John Owen’s life reminds us that Christian holiness is not achieved by our own strength, intellect, discipline, or success, but through dependence on the Holy Spirit and faithful obedience to God’s Word. As we fight the daily battle against sin, may we turn to Scripture, prayer, and the fellowship of the church, seeking to live out what we know and proclaim the truth of Christ for His glory.

An eight-week journey through the lives of the men God used to reform and revive His Church. From Martin Luther’s stand for justification by faith alone, to the pastoral depth of John Owen and John Calvin, to the revival fire of Jonathan Edwards and George Whitefield, to the gospel clarity of Charles Spurgeon. These were ordinary men gripped by an extraordinary gospel.
