Jesus said, “Surely, I come quickly,” in His closing statement (Revelation 22:20 KJV). It usually means, “without losing any time,” since it will happen anytime soon. Actually the disciples thought Christ would come back during their lifetime or at most during the first century that brought them a sense of urgency.
Throughout history, it is almost this principle that has been applied regardless of a good intention or a bad intention.
The Gospel of Matthew describes the end time events; however, those events happen almost all the time throughout the history. Only warning sign we can learn from those events in the Bible is an intensity of events which has never happened before.
Are those events political and economic? What about the time of Jesus on earth? The people missed Jesus the Messiah by an earthly king, or an armor of God, or a political hero who would turn the evil society upside down. We might miss Him again when He returns if we see Him in the same manner.
There are two basic measurements to know and expect when the end comes. One is “And this gospel of the kingdom shall be preached in all the world for a witness unto all nations [ethnos]; and then shall the end come” (Matthew 24:14 KJV). The other is to see the Nation of Israel as a world timetable. – T
