The seven seals of the book of Revelation have been studied and restudied throughout the history of the Christian church. Many different approaches have been used to interpret the meaning of Revelation’s passages. In Heaven’s Open Door, author Erwin R. Gane seeks to consider the seals of Revelation in relation to the ministry of our heavenly High Priest. Christ’s mediatorial and judgment ministries have definite bearing not only on the time in which the seals apply but also in the nature to the events and messages described. The author accepts the principle that the Bible is its own interpreter and seeks to study with this principle in mind. He believes the Lord has given us a thoroughly consistent message throughout the Scriptures that readers can understand.
