John Owen is widely hailed as one of the greatest theologians of all time. His many works--especially those encouraging Christians in their struggle against sin--continue to speak powerfully to readers today, offering much-needed spiritual guidance for following Christ and resisting temptation day in and day out. Starting with an overview of Owen's life, ministry, and historical context, Michael Haykin and Matthew Barrett introduce readers to the pillars of Owen's spiritual life. From exploring his understanding of believers' fellowship with the triune God to highlighting his teaching on justification, this study invites us to learn about the Christian life from the greatest of the English Puritans.
