Why did Jesus have to be born of a virgin?
In the slave market only a freeman could purchase a slave. Mankind has been a slave to sin since the fall of Adam and Eve. Only a man free from sin could purchase mankind from the slave market of sin.
Jesus had to have a human body to live as a man and to live a sinless life. His blood could not be human or He would inherit the same sin nature as the rest of mankind. Nary provided Jesus’ human body but the blood that ran through His veins was not human blood from an earthly father but God’s blood, pure and sinless. He was the only man ever born free of sin.
But there was a further reason why the virgin birth was essential. Jesus was born of the royal line of David and was the rightful heir to the throne of Israel. At the time of Jesus’ birth, Israel had a King called Herod but he wasn’t even Jewish. There had not been a king of the line of David on the throne since Judah went into captivity in Babylon, when Nebuchadnezzar conquered Jerusalem and Judah around 600 BC. At the time of Nebuchadnezzar’s invasion the King of Judah, who was of the royal line of David, was King Jehoiachin, or Coniah for short. He disobeyed God and God cut off Coniah from the throne of Judah and he was taken to Babylon along with all the princes, the royal court and most of the people of Judah.
But God went further and put a curse on Coniah. We can read it in Jeremiah 22:28 – 30. The curse said that none of Coniah’s descendents would ever sit on the throne David. As God had already prophesied that Messiah would be King forever over Israel, this curse would appear to be an insurmountable obstacle. But nothing is impossible to God.
Mary was of the line of David through his son Nathan but Joseph was of the royal line of David, Of the seed of Coniah. But Jesus was not Joseph’s natural son and so did not bear the curse of Coniah. In those days both Roman and Hebrew father’s ‘adopted’ their own son’s. This was a different concept from adoption as we know it in our society. The father had to perform two tasks. He had to name the child and to train him in a trade. By the time the child grew up he would be expected to be given the responsibility of representing his father in business. An angel appeared to Joseph to tell him to call the Child’s name Jesus ( or Yeshua as it was in Hebrew) and Joseph taught Yeshua his trade as a carpenter.
Jesus was Joseph’s first son and so inherited the throne of David through Joseph but not the curse of Coniah. The virgin birth was essential.
In Matthew 1:16, it says “Joseph the husband of Mary of whom was born Jesus who is called Christ”. The form of the verb “born” is feminine singular which means “born only of Mary”.
Jesus will reign as King, forever, when He returns.
