Matthew 24:23-25

23At that time, someone may say to you, “Look, here is the Messiah.” Or they may say, “There he is!” When they say that, do not believe them.

24Some people will say to you, “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.

25So be careful! I have told you about these things before they happen.
