Matthew 11:23
Then Jesus began to denounce the cities in which most of his miracles had been performed, because they did not repent.
That the Messiah performed miracles, did not always lead to people repenting from their sins. He came back and rebuked the cities that had seen His most awesome powers. Jesus was not sent to Earth to join a spiritual competition to see who would perform the biggest miracles. He came to pay the perfect atonement for our sins, pouring out His blood at the cross in Jerusalem. Be aware that Satan also has been given the power to deceive people with miracles. God has given Satan such powers to test us.
