Matthew 24:21-27

For at that time there will be a great tribulation (pressure, distress, oppression), such as has not occurred since the beginning of the world until now, nor ever will [again]. [Dan 12:1; Joel 2:2] And if those days [of tribulation] had not been cut short, no human life would be saved; but for the sake of the elect (God’s chosen ones) those days will be shortened. Then if anyone says to you [during the great tribulation], ‘Look! Here is the Christ,’ or ‘There He is,’ do not believe it. For false Christs and false prophets will appear and they will provide great signs and wonders, so as to deceive, if possible, even the elect (God’s chosen ones). Listen carefully, I have told you in advance. So if they say to you, ‘Look! He is in the wilderness,’ do not go out there, or, ‘Look! He is in the inner rooms [of a house],’ do not believe it. For just as the lightning comes from the east and flashes as far as the west, so will be the coming [in glory] of the Son of Man [everyone will see Him clearly].
