This book is part of an eight volume set of expositions on the book of Ephesians by David Martyn Lloyd-Jones. Lloyd-Jones was one of the very best expositors of the twentieth century. If Lloyd-Jones wrote it it is worth reading and studying repeatedly. This volume deals with the subject of unity in the "Body of Christ;" his church. Unity in the church is, in fact, the overwhelming theme of the book of Ephesians. It "echoes" the prayer of Jesus found in the book of John. Excellent, excellent read. I recommend it to every serious bible student. ( )
