Christians surveying the world have been wondering for some time now if we've entered the final phase of existence -- if it's Revelation Time. But it's not just Christians who are wondering that question. Plenty of non-believers, on-the-fence believers, secularists and humanists and atheists are discussing the idea of the end of humanity, too. The Bible gives the signs and seasons to watch to predict the ending times, but specifically states that no one but God knows the exact date. Still, there's a lot going on today that would seem to suggest the end days are getting nearer; that the time of the rapture is approaching with a rather astonishing speed. Dr. Michael Youssef, pastor and scholar, discusses if the end is near -- and his new, aptly titled, "Is the End Near? What Jesus Told Us About the Last Days" book.
