Matthew 24:21-22, 29-31

For this will be a time of great misery beyond the magnitude of anything the world has ever seen or ever will see. Unless God limited those days, no one would escape. But because of his love for those chosen to be his, he will shorten that time of trouble.

“Then immediately this is what will take place: ‘The sun will be darkened and the moon give no light. The stars will fall from the sky and all the cosmic powers will be shaken.’ Then the sign announcing the Son of Man will appear in the sky, and all the nations of the earth will mourn over him. And they will see the Son of Man appearing in the clouds of heaven, revealed with mighty power, great splendor, and glory. And he will send his messengers with the loud blast of the trumpet, and with a great voice they will gather his beloved chosen ones from the four winds, from one end of heaven to the other!”
