In The Harbinger: Fact or Fiction? author David James exhaustively documents and responds to the serious flaws found throughout the New York Times best-seller from Charisma Media, The Harbinger. Messianic rabbi Jonathan Cahn believes he has discovered an "ancient mystery" in Isaiah 9:10 that "explains everything from 9/11 to the collapse of the global economy." As Cahn states at the beginning of his book "What you are about to read is presented in the form of a story, but what is contained within the story is real." Many have accepted Cahn's message as being genuinely from God. However, David James has clearly demonstrated that The Harbinger falls far short of meeting the biblical requirements for such a message from God, being based on the mishandling of Scripture, faulty theology, misleading statements, the selective use of historical facts, and unsupported speculation.
