I’ve seen several people try to say that Jesus was born of a virgin so that He could avoid inheriting “original sin”, assuming that sin is transmitted somehow through the father, and not the mother.
This is an assumption that has no basis in the Bible. It’s an attempt to hold to the unbiblical doctrine of inherited sin.
In bringing many sons to glory, it was fitting that God, for whom and through whom everything exists, should make the author of their salvation perfect through suffering. Both the one who makes men holy and those who are made holy are of the same family. So Jesus is not ashamed to call them brothers. He says,
"I will declare your name to my brothers;
in the presence of the congregation I will sing your praises."
"I will put my trust in him."And again he says,
"Here am I, and the children God has given me."
Since the children have flesh and blood, he too shared in their humanity so that by his death he might destroy him who holds the power of death—that is, the devil— and free those who all their lives were held in slavery by their fear of death. For surely it is not angels he helps, but Abraham's descendants. For this reason he had to be made like his brothers in every way, in order that he might become a merciful and faithful high priest in service to God, and that he might make atonement for the sins of the people. Because he himself suffered when he was tempted, he is able to help those who are being tempted.
“It was fitting”
Only someone who has been sinned against can forgive the offender. You can forgive me if I sin against you, but you can’t forgive me if I sin against my boss.
Since we have all sinned against God, only God can forgive us.
And God wants to show mercy on us and forgive us. However, every time He forgives sin, He is compromising His justice. There needs to be something that takes the place of justice. That’s called “atonement”.
God provided the nation of Israel a means of atonement through the sacrificial system. But no animal, (or man) no matter how innocent it may be, is inadequate in atoning for our sin against God.
The only sufficient atonement would be if God Himself became that atoning sacrifice.
Since it was humanity that sinned against God, it was fitting that God become a man.
Jesus was conceived by the Holy Spirit (remaining divine) and born of a woman (becoming a man) so that He could become the only eternally sufficient atoning sacrifice.
