The purpose of this commentary is not only to provide the reader with exegetical and background information on the text but to help the reader trace the theological threads that tie the book together. Therefore, there is a great deal of intertextual data in the book, and on key words I provide the reader with an overview of the term and related terms throughout the Apocalypse (I use “Apocalypse” and “Revelation” interchangeably for variety) along with theological commentary on the theme in the book.
