Matthew 24:20-25

24:20 Pray that your flight may not be in winter or on a Sabbath. 24:21 For then there will be great suffering unlike anything that has happened from the beginning of the world until now, or ever will happen. 24:22 And if those days had not been cut short, no one would be saved. But for the sake of the elect those days will be cut short. 24:23 Then if anyone says to you, ‘Look, here is the Christ!’ or ‘There he is!’ do not believe him. 24:24 For false messiahs and false prophets will appear and perform great signs and wonders to deceive, if possible, even the elect. 24:25 Remember, I have told you ahead of time.
