Jesus was so different from the Messiah people expected, even John the Baptist had moments where he wondered if Jesus was the Messiah. If he’s really a prophet, how could John become confused? In this passage, Jesus answers that question.
John the Baptist
Matthew shifts his focus to the how people respond to Jesus. Most reject him. Even John the Baptist becomes confused, because Jesus is not acting like the Messiah he expected.
John the Baptist was the herald who announced the coming of the King. His message had two parts: repent for the kingdom of God is at hand. The king is coming. It is time to turn back to God and follow his Messiah.
