Craig A. Koester’s commentary on Revelation seeks after what Karl Barth referred to as the ‘strange new world within the Bible’. He seeks to locate the book fundamentally within the ancient conflict between the confession of Jesus as Lord and the Roman imperial cult. In the process, the reader comes to appreciate where the history of interpretation has detoured from the book’s original purpose. There are throughout the commentary a number of theological issues raised. Noteworthy are soteriology (the triumph of grace) and pneumatology (the meaning of the seven spirits). The essay seeks to explore these themes.
