The Foundation of Communion with God introduces readers to the Trinitarian piety of John Owen (1616-1683). Ryan McGraw's introduction to Owen sketches the major events of this important theologian s life and shows how his circumstances shaped his thought on the themes of the Trinity and public worship. The second part of the book presents forty-one brief selections from Owen's writings that trace his thoughts on knowing God as triune, on Scripture and worship, on heavenly-mindedness, and on covenant and the church.
