Jesus chided the hypocrites of his day who were intelligent enough to observe the sky phenomenon and forecast the weather, but when it came to discerning that the events of the day indicated that the Jewish system of things was entering a period of judgment, they were clueless. Similarly, many respected observers today point to numerous indications that the present system is facing extreme difficulty in the near term. Of course, they are completely unaware that Jehovah God foretold the the complete meltdown of the system, but at least they are astute enough to see the storm as it developes. Apostates on the other hand demonstrate a blindness so complete is as to astound. / You Know
