Have you looked at it from the “New Adam” and the “New Eve” viewpoint?
Because of our original parents, Adam and Eve, sin, death, toil, pain in childbirth, etc. etc. was ushered into the world. The gates of Heaven were closed to us. The ultimate grounding. But, even at our darkest hour, God didn’t leave us with despair. He said, “I will put enmities between thee and the woman, and thy seed and her seed: she shall crush thy head, and thou shalt lie in wait for her heel.” (Genesis 3:15, D-R)
This was the first prophesy of Jesus’ Incarnation. But there was still a whole lot of suffering and sinning and selfishness and general evil that we had to wade through. But we brought it on ourselves.
Then, in some tiny town in a backwater place occupied by a foreign power, a girl is offered a choice. She, like, Eve, has the choice that will offer Life or (continued) Death to all people. Mary, knowing full well what could happen to a girl pregnant outside of wedlock (death) and the horrifying manner in which it could occur (stoning), fully trusted in God, His Mercy, His Will, and His Love, and said “Yes”.
Her Fiat allowed the Incarnation to be born, and, as the New Adam, act in perfect obedience to God the Father, even unto death. His sacrifice opened the gates of Heaven again. Mary’s sacrifice showed us how true Christians are meant to be.
Every Apostle, every other disciple, every saint sinned at some point. Peter denied Our Lord three times. Paul killed Christians, St. Francis was a rich playboy. As someone said, Mary is humanity’s sole boast. She is the only one, thanks to the singular privledge of the Immaculate Conception, who always put God first. That’s why we heap so much praise and honor on her. Not to slight others, but to praise the creature that is, in a sense, God’s masterpiece.
