Bible Prophecy Under the Microscope-Episode 83 Gary responds to a Facebook video where an individual claims that the Gospel must be preached in the "whole world" before the end comes. This promise comes from Matthew 24:14 and is constrained by the timeframe of Matthew 24:34. Gary points out that the phrase doesn't mean the entire world as we know it today, as well as several verses proving that the Gospel was preached "in all the world" before that first-century generation came to pass.
