Berean Research has the story:
Can you judge a book by its cover? If the statements made by any Bible teacher are to be biblical, than perhaps we ought to be Bereans to examine said cover. The often-controversial Rabbi Jonathan Cahn has published a new book titled, The Book of Mysteries, that comes out in a few weeks, and already there are three rather interesting declarations we are going to examine.
The author, Jonathan Cahn, wrote The Harbinger and The Mystery of the Shemitah. Additionally, Cahn has given himself the title of Prophet, claiming direct, extrabiblical revelation from God for the Church, as his biography states: “JONATHAN CAHN is known throughout the world as a prophetic voice for this generation and for the opening up of the deep mysteries and treasures of God.” Source.
