The book of Matthew is the first book of the New Testament and the first of the Gospels to be written by one of the disciples of Jesus. Matthew testifies to the sacred lineage of Christ, proving His legitimacy as the Messiah and the Son of God. It also contains the story of Jesus' life, from His conception to His resurrection, making this book a wonderful transition from the Old Testament to the New, as it demonstrates the fulfillment of the prophecies regarding the Messiah.
