Fallen Angels Comes As False Christs and False Prophets Before Christ Returns

Matthew 24:23-24
King James Version
23 Then if any man shall say unto you, Lo, here is Christ, or there; believe it not.

24 For 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.
