Matthew 24:21-23

21 For then there will be great distress, unequaled from the beginning of the world until now—and never to be equaled again.

22 “If those days had not been cut short, no one would survive, but for the sake of the elect those days will be shortened.

23 At that time if anyone says to you, ‘Look, here is the Messiah!’ or, ‘There he is!’ do not believe it.
