At the Wedding Feast of Cana, the wine ran short. Weddings in Jewish tradition would last easily a week, so a shortage, especially early on, would be catastrophically embarrassing for the couple.
Mary, ever the watchful mother, notices immediately that the wine has run short and she does what we should always do; she turns to Jesus.
Jesus’ response – “Woman, what does this have to do with me? My hour has not yet come” (John 2:4) – sounds harsh, but in the full context, Mary doesn’t take this as a rebuke. She goes with perfect trust to the servants and says to them “Do whatever He tells you” and Jesus does indeed perform a miracle, turning hundreds of gallons of water into the finest wine.
Mary had never seen Jesus perform a miracle, yet she believed that He could. And that He would.
Mary is gently pushing Jesus into His public ministry so He can begin His Messianic purpose. She knows her Bible, she knows what the prophets have foretold. One commentator I read notes that Mary is interceding not just for the couple, and not just as a foretelling of her intercession for us all the time, but that Mary is saying Israel has no wine – they need Jesus to start His ministry.
These are also the last recorded words that Mary says in the Bible, said to servants. She is saying these words to you. Do whatever He tells you. Do it. Whatever it is. Listen to God. When He speaks to you, don’t harden your heart. He has a plan just for you that only you can accomplish; “plans for welfare and not for evil, to give you a future and a hope” (Jer 29:11)
