This loop begins in Genesis 3:15 NIV: "And I will put enmity between you and the woman, and between your offspring and hers; he will crush your head and you will strike his heel." So it begins, the search for the one who would crush the head of the serpent, Satan. Who is searching? Everyone, especially the Woman, was looking for that off-spring who would be the deliverer. There were shadows of that deliverer. We saw can see it now in the stories of Isaac, Moses, Samson, Samuel, and so many others. They were men who born to deliver their people from oppression, to crush the head of their oppressors. Yet, none could crush the head of Satan; none could satisfy our need to regain the immortality we lost.
None accept Jesus.
I found it odd when he addresses his mother as "woman" in John 2. Now, I think he speaks for every "son" whose parents have looked to him to be their savior from shame, futility, and the grave. She calls him to save a marrying man and his family from shame in saying, "They have no more wine." Luke 2:3 NIV. He responds "Woman why do you involve me?" "My hour is not yet come." (Luke 2:4). Yet he responds, he saves the bridegroom and his family from shame in the ensuing verses, 5 - 11.
He speaks for every son and daughter who could not save their parents from death, futility, and shame. Perhaps, they could not save because it was not time for THE Savior. Perhaps they could not save because they were not THE Savior. Perhaps both were true.
In addressing her as "woman." I think he is identifying her with the first person to referred as "woman" because it was her first name: Eve. I think he is beginning to close the loop.
On the cross, he does close the loop. The search for the "offspring" of Genesis 2:15 is over. Parents no longer have to look at their children, searching for and sometimes seeing a deliverer. The only deliver a man or woman needs was on that cross delivering them. He delivered them as he closed the loop. He says to his mother, ""Woman, here is your son," and to the disciple, "Here is your mother."" (John 19: 26-27).
Now each son and daughter is just that, a son or a daughter, none them have to be a deliverer. Each mother and father are just that, a mother and a father not victims and slaves needing to be rescued. They already have been rescued, by and through their union with Christ.
The search is over. The loop is closed.
John 20:15, the risen Jesus says, "Woman, why are you crying? Who is it you are looking for?" He then makes the same shift Adam did in the garden. (He went from calling his wife "woman," to naming her, Eve (Genesis 3:20).) He calls her "Mary." She turns to him, recognizing him, and cries out "Rabboni!" She has found him: her teacher, her lord, her friend, and now her Savior.
Our search is over. We have a Savior and no longer need to search for another. His name is Jesus and that is wonderful.
