Matthew 1: 18-25
Now the birth of Jesus Christ took place in this way. When his mother Mary had been betrothed to Joseph, before they came together she was found to be with child from the Holy Spirit. And her husband Joseph, being a just man and unwilling to put her to shame, resolved to divorce her quietly. But as he considered these things, behold, an angel of the Lord appeared to him in a dream, saying, “Joseph, son of David, do not fear to take Mary as your wife, for that which is conceived in her is from the Holy Spirit. She will bear a son, and you shall call his name Jesus, for he will save his people from their sins.” All this took place to fulfill what the Lord had spoken by the prophet:
“Behold, the virgin shall conceive and bear a son, and they shall call his name Immanuel – (which means, God with us).
When Joseph woke from sleep, he did as the angel of the Lord commanded him: he took his wife, but knew her not until she had given birth to a son. And he called his name Jesus.
A betrothal in the custom of the day was almost a wedding but with no sexual rights. So when Joseph discovered that Mary was pregnant he knew the father wasn’t him, and thus as an upright man he sought to get out of the arrangement. Of course others got to know about this unexpected pregnancy, but whereas Joseph had an angelic messenger to explain things to him the general populace didn’t. This led to the Pharisees later on saying that they didn’t know where Jesus was from. Maybe a Roman soldier rape-case? They used it as an insult by saying “we know our fathers, but we don’t know where you came from!”. But Joseph got to know the truth of the matter. So Mary and Jesus had a husband/father provider and the birth was to create the God-man Jesus. Fully man – fully God. A lot of Christian doctrine hangs on this Virgin Birth.
Prayer: If this is true, then please let me look into the story thoroughly.
