The Book of Matthew is the first book of the New Testament of the Bible, and the first of the Four Gospels.
In a nutshell, the Book of Matthew has 28 chapters that include the following: the ancestry and the birth of Jesus, escape to Egypt, Herod's order to kill the children, the return from Egypt; the preaching and message of John the Baptist; the baptism and temptation of Jesus by the Devil; Jesus begins work in Galilee; Jesus goes from Galilee to Jerusalem – Jesus chooses his 12 disciples and instructs them what to do, Jesus teaches and preaches through stories and parables, Jesus heals, and Jesus delivers the Sermon on the Mount; the last week of Jesus – the last supper, his trial and death; and the resurrection of Jesus from his death, that he is alive.
One important idea stressed over and over in the book of Matthew is that God expects his people to obey him. Matthew wants it understood in the teachings of Jesus. He also wanted to help people grow in their faith. Some of these are found for example, when Jesus was baptized by John the Baptist he says, "We must do all that God wants us to do." Chapter 3, verse 15; in the Sermon on the Mount about what the people of God must do to obey him, and when Jesus reminds the leaders and chief priests that John the Baptist showed them how to do right.
Matthew provided a record of the message of Jesus and his ministry while on earth. Matthew pointed out about the coming of Jesus as the Messiah aligned to the prophecies of the Old Testament Scriptures.
The book ends in chapter 28 last two verses with the parting words of Jesus, his instructions what the disciples should do as he leaves them, and with the most poignant promise of "… and I will be with you always, until the end of the world."
