We pay attention to powerful voices -- in the media, on the radio, and even in the wilderness. John the Baptist was one of those voices that demanded attention. He spoke of God's coming kingdom and favor for those who sought his forgiveness. John serves as an important pivot between OT expectation and Jesus's messianic ministry. When Jesus comes to him to receive baptism, the scene closes with the arresting voice of the heavenly Father, who deserves the last word on His Son.
