In the New Testament of the Bible, Jesus is described as being the Messiah (Christ) who was promised by the prophets of the Old Testament of the Bible. Jesus is fully God and fully human. God allowed himself to be born as a person, to live among people and to teach people about God's plan of salvation and to die for our sins. Because Jesus also is human, he is called the Son of God and the Son of Man.
Jesus was born to a woman named Mary about 2000 years ago in the town of Bethlehem, which is near Jerusalem, in the Biblical land of Israel. Mary was engaged to a man named Joseph. In Matthew 1:20, Joseph is called a "son of David," meaning he is a descendant of King David, who ruled over Israel about 3000 years ago.
Mary was a virgin when she became pregnant with Jesus. The miracle of the virgin birth of Jesus is recorded in the gospels of Matthew and Luke in the New Testament of the Bible. In the Gospel of Matthew, it says:
But after he had considered this, an angel of the Lord appeared to him in a dream and said, "Joseph son of David, do not be afraid to take Mary home as your wife, because what is conceived in her is from the Holy Spirit. She will give birth to a son, and you are to give him the name Jesus, because he will save his people from their sins."
All this took place to fulfill what the Lord had said through the prophet: "The virgin will conceive and give birth to a son, and they will call him Immanuel" (which means "God with us").
When Joseph woke up, he did what the angel of the Lord had commanded him and took Mary home as his wife. But he did not consummate their marriage until she gave birth to a son. And he gave him the name Jesus.
