“Against the backdrop of a world increasingly hostile to Christianity, the author solidifies his church’s identity as the true people of God, who transcend ethnic, economic, and religious barriers to find oneness in their adherence to Jesus Messiah. His Gospel becomes a manual on discipleship, as Jew and Gentile are made disciples of Jesus Messiah and learn to obey all that he commanded his original disciples.”
(NIV Application Commentary)

“Right at the beginning, the genealogy is to prove that Jesus is the Son of David (1:1–17). The title, Son of David, is used more often in Matthew than in any other gospel (15:22, 21:9, 21:15). The wise men come looking for him who is King of the Jews (2:2). The triumphal entry is a deliberately dramatized claim to be King (21:1–11). Before Pilate, Jesus deliberately accepts the name of King (27:11). Even on the cross, the title of King is affixed, even if it is in mockery, over his head (27:37). In the Sermon on the Mount, Matthew shows us Jesus quoting the law and five times abrogating it with a regal: ‘But I say to you …’ (5:22, 28, 34, 39, 44). The final claim of Jesus is: ‘All authority … has been given to me’ (28:18). Matthew’s picture of Jesus is of the man born to be King. Jesus walks through his pages as if in the purple and gold of royalty.”
