Here is a modern reader-s edition of a classic Puritan work by a classic Puritan author. It is a powerful Trinitarian profiling from Scripture of the truth that fellowship with God is and must ever be the inside story of the real Christian-s life. John Owen is a profound teacher on all aspects of spiritual life, and it is a joy to welcome this reappearance of one of his finest achievements.- J. I. Packer, Professor of Theology, Regent College
