This book has a riveting spell on me since I first read it a decade ago and has continued to shape the fundamental landscape of my understanding of theology and spirituality ever since. He traces his conversion from atheism to his reading of Thomas Merton's Seven Storey Mountain, that led him to a journey of spiritual inquiry, where he met Christians of different shades and backgrounds. It was however the Reformed tradition/Puritans that had the most profound impact on him and opened him up to the transforming power of the gospel.
He sees a missing link between justification and sanctification among many believers which he dubs the 'sanctification gap'. He sees how it is possible to have confessed Christ, continue a life of religiosity and remain spiritually dead. In fact, either an encounter with the grace of God without an ensuing commitment to sanctification or an exposure to the righteous demands of God's law without a concomitant experience of his grace can lead to aberrant forms of the Christian life. He offers a way forward by explicating how justification and sanctification are brought together conceptually and in practice.
Presenting his understanding from the Reformed perspective, he outlines the fundamental core of the gospel message that can truly set us on a vibrant course of growth and renewal. This includes depth conception of sin, and encounter with the life-transforming grace of God, justification as well as sanctification by faith, an experience of God's complete acceptance of us through the righteous achievements of Christ, claiming our authority through Christ's defeat over the diabolic, prayer and complete reliance on the Spirit, disenculturation (freedom from cultural binds)of our faith and theological integration.
He includes some additional musings on music, eschatology, live orthodoxy and Christian social concern, each of which is inspiring and thought provoking. I have found the book to be beautiful and succint in its expression and spiritually and theologically challenging. He has written a simpler version of this book with discussion questions more recently for the benefit of some who found this original work less accessible but I have found that it is nothing like reading and drinking in again and again Lovelace's very fine book 'Dynamics of Spiritual Renewal' in all its depth and beauty.
