What is the perspective in the nonfiction book, The Harbinger: The Ancient Mystery That Holds the Secret of America’s Future?

The Harbinger is told from the perspective of Nouriel, the main character and the man called as the scribe for the novel's unnamed prophet. Nouriel seems to be the fictional version of the author, Jonathan Cahn, as he mentions his intention to write his story in the form of a narrative, indicating that this book is the narrative he has written to share the message he received from the prophet concerning the Nine Harbingers. The author uses Nouriel's perspective to tell the story because only Nouriel knows the details of the time he spent with the prophet, and as such, only he can report on the meanings behind the seals of the harbingers. Additionally, his narrative is set in a frame story centering around his retelling of his story to Ana, and this serves to allow him to answer Ana's questions and dispel her doubts in place of the reader.
