Mark 13:21-23

21At that time, someone may say to you, “Look, here is the Messiah!” Or they may say, “Look, he is there!” If they say that, do not believe them.

22Some people will even say, “I am the Messiah.” Other people will say, “I am a prophet from God.” But their words will be false. They will do strange and powerful things for people to see. If possible, they would even deceive the people that God has chosen.

23So watch out! I have told you about all these things before they happen.
