19 For the trouble of those days will be far worse than any the world has ever known from the very beginning when God created the world until the present time. Nor will there ever be anything like it again.
20 But the Lord has reduced the number of those days; if he had not, nobody would survive. For the sake of his chosen people, however, he has reduced those days.
21 “Then, if anyone says to you, ‘Look, here is the Messiah!’ or, ‘Look, there he is!’ — do not believe him.
22 For false Messiahs and false prophets will appear. They will perform miracles and wonders in order to deceive even God's chosen people, if possible.
23 Be on your guard! I have told you everything before the time comes.
24 “In the days after that time of trouble the sun will grow dark, the moon will no longer shine,
25 the stars will fall from heaven, and the powers in space will be driven from their courses.
