21For then shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be. 22And except those days should be shortened, there should no flesh be saved: but for the elect's sake those days shall be shortened. 23Then if any man shall say unto you, Lo, here is Christ, or there; believe it not. 24For there shall arise false Christs, and false prophets, and shall shew great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect.25Behold, I have told you before. 26Wherefore if they shall say unto you, Behold, he is in the desert; go not forth: behold, he is in the secret chambers; believe it not. 27For as the lightning cometh out of the east, and shineth even unto the west; so shall also the coming of the Son of man be.
