In Context

20 If the Lord had not cut short those days, no one would survive. But for the sake of the elect, whom he has chosen, he has shortened them.

21 At that time if anyone says to you, 'Look, here is the Christ !' or, 'Look, there he is!' do not believe it.

22 For false Christs and false prophets will appear and perform signs and miracles to deceive the elect--if that were possible.

23 So be on your guard; I have told you everything ahead of time.

24 "But in those days, following that distress, " 'the sun will be darkened, and the moon will not give its light;

25 the stars will fall from the sky, and the heavenly bodies will be shaken.'
