Mark 13:21-22

21Then if anyone says to you, ‘Look, here is the Christ (the Messiah, the Anointed)!’ or, ‘Look, He is there!’ do not believe it;

22for false Christs and false prophets will arise, and they will provide signs and wonders in order to deceive, if [such a thing were] possible, even the elect [those God has chosen for Himself].
