The Bible
The Gospel of Matthew presents Jesus as the long awaited Messiah who fulfills Old Testament prophecy and ushers in the radical, unexpected Kingdom of Heaven.
Matthew uses the unique phrase 'kingdom of heaven' to emphasize the contrast between God's radical ways and the flawed structures of human society.
The genealogy and birth narrative legally establish Jesus as the Davidic heir while showing that God's plan intentionally includes outsiders and Gentiles.
John the Baptist serves as the prophetic forerunner who prepares the way for the Lord but recognizes his own complete inferiority to the Messiah.
