Biblical Literature, Purpose and theme

The Revelation (i.e., Apocalypse) to John is an answer in apocalyptic terms to the needs of the church in time of persecution, as it awaits the end-time expected in the near future. The purpose of the book is to encourage and admonish the church to be steadfast and endure. The form of an apocalypse shows affinities with contemporary Jewish, Oriental, and Hellenistic writings
