BTW, I have read the Harbinger. Regardless of what people think about it, one cannot deny the series of "coincidences" that are not really coincidences! I know we are supposed to always be ready, but very specially we need to be ready to face our Savior in the coming months. Oh, what a day that will be!!
Jonathan Cahn wrote a sequel to the Harbinger, called The Mystery of the Shemitah. I highly recommend it. It goes into a lot more detail.
