The book of Revelation firstly reveals Christ (1:1), and secondly the testimony of Jesus (1:2). In other words, this book is concerned with Christ and the church. In Revelation, Christ and the church are revealed in a unique and particular way. Several aspects of Christ, such as the vision of Him as the High Priest in the midst of the churches, caring for them in love yet with a judging attitude (1:13-16), the vision of Him as the Lion-Lamb in the midst of God’s throne, and of the four living creatures and in the midst of the 24 elders of the universe opening the seven seals of God’s universal administration (5:1-6:1), and the vision of Him as Another Mighty Angel coming down from heaven to take possession of the earth (10:1-8; 18:1) have never been unveiled as they are in the book of Revelation. In this book, the revelation of Christ is unique and ultimate. In addition to this ultimate revelation of Christ, the book of Revelation also unveils many unique aspects of the church as the testimony of Jesus. The lampstands in chapter one, the great multitude of the redeemed in chapter seven, the bright woman with her man-child in chapter 12, the harvest with its firstfruits in chapter 14, the overcomers on the sea of glass in chapter 15, the bride ready for marriage and the fighting army of Christ in chapter 19, and the New Jerusalem in chapters 21 and 22 are all the testimony of Jesus which is the Spirit - the substance, the disposition, and the characteristic - of the prophecy in this book (19:10). The central content of this book is an unveiling of God’s economy concerning Christ and the church, presenting the ultimate and consummate revelation of Christ with His full salvation and the church as His loving bride, the New Jerusalem. In this book, we find the full and adequate conclusion, not only to the writings of John and to the New Testament, but also to the entire divine revelation.

In the Lord’s recovery during the past five hundred years the church’s knowledge of the Lord and His truth has been continually progressing. This monumental and classical work by Brother Witness Lee builds upon and is a further development of all that the Lord has revealed to His church in the past centuries. It is filled with the revelation concerning the processed Triune God, the living Christ, the life-giving Spirit, the experience of life, and the definition and practice of the church. In this set Brother Lee has kept three basic principles that should rule and govern every believer in their interpretation, development, and expounding of the truths contained in the Scriptures. The first principle is that of the Triune God dispensing Himself into His chosen and redeemed people; the second principle is that we should interpret, develop, and expound the truths contained in the Bible with Christ for the church; and the third governing principle is Christ, the Spirit, life, and the church. No other study or exposition of the New Testament conveys the life nourishment or ushers the reader into the divine revelation of God’s holy Word according to His New Testament economy as this one does.

John’s writings are complementary to the entire divine revelation. This means that the writings of John complete the Bible. His Gospel completes the Gospels, his Epistles complete the Epistles, and his Revelation completes the whole Bible. In the Life-study of the Epistles of John, Witness Lee emphasizes the outstanding matters in these Epistles in relation to the economy of God. Some of these matters include the divine life and its fellowship, the anointing, the divine birth and the divine seed, the walk in truth and in love, and the encouragement of the fellow workers in the truth. In the Life-study of Jude, Witness Lee shows from Jude's Epistle the genuine contending for the faith and the believers' living in the Triune God issuing in their full enjoyment of Him.
