Matthew 24:23 Meaning

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.
