The book of the generation of Jesus Christ, the son of David, the son of Abraham.
Matthew wrote these words to declare that Jesus indeed is the Christ. Jesus is God with us, to save. Jesus is Joshua in Hebrew which means "the LORD saves" or "the LORD is salvation". Christ means the "anointed one". He is the chosen Messiah who would deliver the people from life's greatest enemies (sin and death) by victoriously fulfilling Israel's 3 leadership offices; Prophet, Priest & King. Being the Son of David, he is the promised King who would rule an everlasting kingdom by defeating their enemies and at the same time bring healing to the people. The Son of David offers strength to the weak and the wounded. Jesus is also called the son of Abraham. Abraham started as a pagan before God called him and promised him that all nations will be blessed through his offsprings. Matthew ended the book with the idea that Jesus will bless the nation by commanding the apostles to make disciples of "all nations". Truly all spiritual children of Abraham (whether Jew or Gentile) who are the true disciples of Jesus Christ will be blessed.
Is Jesus "God with you"? Is He your Savior? Is He the King who rules your heart? Is He the God who saves all who would repent, whether you be Jew or Gentile? Again, who is Christ to you?
