Matthew 24:24-27

24For there shall arise false Christs, and false prophets, and shall show great signs and wonders; so as to lead astray, if possible, even the elect. 25Behold, I have told you beforehand. 26If therefore they shall say unto you, Behold, he is in the wilderness; go not forth: Behold, he is in the inner chambers; believe it not. 27For as the lightning cometh forth from the east, and is seen even unto the west; so shall be the coming of the Son of man.
