The first is from St. John of the Cross.
The discreet lover does not care to ask for what she lacks and desires, but only indicates this need so the Beloved may do what he pleases. When the Blessed Virgin spoke to her beloved Son at the wedding feast at Cana in Galilee, she did not ask directly for the wine, but merely remarked: “They have no wine”.
- Commentary on The Spiritual Canticle 2.8
Not much more to say here. St. John pretty much summarizes things nicely. Mary provides us with the perfect model (and example) of intercession.
Then there is this short phrase we find in St. John's gospel -- it's from the Wedding at Cana. Our Lady's words are:
Do whatever he tells you.
-- Jn. 2:5
Interestingly, these words of Mary are almost exactly those of God the Father at Jesus's Transfiguration. As yesterday (8/6/2022) was the Feast of the Transfiguration, it is timely:
This is my beloved Son. Listen to him.
-- Mark 8:7
Mary echoes the words of God. It occurs to me (please forgive me if what I say is theologically flawed or lacking / Me disculpo si digo algo que no tiene razon), she becomes a feminine impersonation of the Divine, of God. An "image of the invisible God, the firstborn of all creation" as St. Paul says (Col. 3:15).
Therefore we must listen to her.
