First published in 1681, The Grace and Duty of Being Spiritually Minded Declared and Practically Improved is John Owen's thorough exposition of the believer's call to set their thoughts and affections on heavenly things. Drawing on Romans 8:6 ("To be spiritually minded is life and peace") and Colossians 3:2 ("Set your affection on things above"), Owen unmasks the stark contrast between minding the flesh and minding the Spirit, showing how spiritual mindedness brings true life and peace. This refreshed edition preserves Owen's complete original text while rendering the language into clear, modern English for twenty-first-century readers. Whether you seek to deepen your communion with God, cultivate a lasting passion for heavenly pursuits, or understand the practical outworking of spiritual renewal, this modern version delivers rigorous theology and actionable insight for every stage of the Christian journey.
