Well, here I am again, ready to give my opinion....
Bear with me....
I believe that the Virgin Birth found in Luke 1:34-35 is parallel to part of the creation story found in Genesis 1:1-3.
The following is strictly my opinion.
In the beginning God had made the universe, but it wasn't "habitable". It was "void" and lifeless.
The Holy Spirit was "brooding"...in my mind that is similar to pacing back and forth just waiting....waiting for what?
Waiting for the voice of God to speak.
God said, "Let there be light." And there was light. What light? The stars and moon and other heavenly bodies didn't "glow" until the 4th day.
What light?
In my opinion, the "light" of holiness and supernatural creativity of God overcame the Earth. In other words, the brooding Holy Spirit brooded no more. He made the universe, the earth primarily "habitable". Sure, it was already created by God and was a physical thing hanging there in space. But now, the Holy Spirit, who was brooding and waiting on God's authority, now made the physical Earth habitable for life and made more than just a physical creation. It was now a vehicle for human kind, creatures meant to have communion with a Holy God. The only Holy God.
God didn't need the planet Earth to have communion with His creation. He could have created us right there in Heaven and kept sin away from our understanding and had perfect communion with us from the get go.
But that wasn't His way or His plan.
The same thing happened to Mary.
When she asked Gabriel how she was going to get pregnant if she hadn't been with a man, he explained the same thing to her.
The same Holy Spirit that made God's created Earth habitable for life with God's permission and by God's command also made her body "habitable" for a supernatural God.
Gabriel told her that the Holy Spirit would "overshadow" her or in my mind "fall" upon her and make the limitations of her physical body now limitless in its ability to nuture God's Son tranformed into physical flesh.
She had been created by God and was a living physical being, but now because of God's authority and command the Holy Spirit made her body more than just a physical creation. It was now a supernatural vehicle for Jesus Christ, Himself.
Jesus could have appeared on the Earth without being a baby first. He didn't need Mary's body to be born in for Him to bring salvation to mankind. Jesus didn't have to be a baby. He could have bypassed the temptations and childhood.
But that wasn't His way nor His plan.
Joseph had absolutely nothing to do with the conception of Jesus Christ. To say that he did is blaphemy, because one is saying that Jesus is not the Holy Son.
Joseph was Jesus' beloved "step-father". Beloved? How do I know when the Bible doesn't speak of their relationship?
I know that Joseph treated him with all of the love of a natural biological father because he treated Mary with dignity and love.
Joseph behaved like a "real" man should with Mary. So therefore, I know that he behaved like a "real" father with Jesus.
Pardon my ramblings.
Peace-
