The transformation of water into wine at the Marriage at Cana or Wedding at Cana is the first miracle attributed to Jesus in the Gospel of John. In the Gospel account, Jesus, his mother and his disciples are invited to a wedding, and when the wine runs out, Jesus delivers a sign of his glory by turning water into wine. Mary recognized the abilities of Jesus doing the impossible, that was why she took the case to him and told everyone to obey and do as he instructs them.
