Rabbi Jonathan Kahn is a frequent guest on the Jim Bakker Show which should tell you something right there. Why is Kahn among a whole host of modern day prophets predicting either the Rapture or the 2nd coming of Christ when the Bible says only God knows? Why all the endless speculation? When it arrives you should be ready for it! Kahn preps with a lot of signs for Jews do request a lot of signs according to 1 Corinthians 1:22.
Most people detest unanswered questions and that gives rise to speculations. The only one that has the answer is God. Were only admonished to WATCH. And that only to Jewish believers.
