This only happened because his mother bugged him about there being no more wine. He had no intention of doing what he did. John 2:3-5;
When the wine ran out, the mother of Jesus said to Him, “They have no wine.” <sup class="versenum">4 </sup>And Jesus said to her, “ <sup class="crossreference" value='(E)'></sup> Woman, <sup class="footnote" value='[a]'></sup> <sup class="crossreference" value='(F)'></sup> what does that have to do with us? <sup class="crossreference" value='(G)'></sup> My hour has not yet come.” <sup class="versenum">5 </sup>His <sup class="crossreference" value='(H)'></sup> mother said to the servants, “Whatever He says to you, do it."
Doesn't this sound like a lot of Moms?
Lets step back and really look at the words that are spoken can we?
John 2:3 And when they wanted wine, the mother of Jesus saith unto him, They have no wine.
Clearly, this is an issue that Mary believes that she and her son can solve.
John 2:4 Jesus saith unto her, Woman,
what have I to do with thee? mine hour is not yet come.
I bolded that part because we see something different with Jesus. Let's go back to when Jesus was a child.
Luke 2:51 And he went down with them, and came to Nazareth,
and was subject unto them: but his mother kept all these sayings in her heart.
We see that when Jesus was a child, he subjected himself to the authority of Mary and Joseph. However, as Jesus starts his ministry he says,
what have I to do with thee.
Ironically, we see the same words being used by the man with daemons.
Mark 5:7 And cried with a loud voice, and said,
What have I to do with thee, Jesus,
thou Son of the most high God? I adjure thee by God, that thou torment me not.
What we see in this language is a clear demarcation. Jesus is no longer under submission to his Mother Mary, but now comes under sole submission to God which announces the beginning of his ministry. Even Legion knew who's son Jesus was. Jesus was the son of God.
There is also a lot more going on with this story. It is not coincidence that the first miracle happens in Cana. I believe that John writes with a known jewish technique. For example, if we look in the Old Testament, we see that the Land of Canaan was the promised land, and it was promised to Abraham. Genesis 12 and 13. However, in chapter 14, we see that he kings joined forces and went to war, and Abram's brother was taken, and Abraham retrieves his beloved brother. And after victory, who is it that Abraham meets but Melchizedek (14:18) and what does the text say? Genesis 14:18 And Melchizedek king of Salem brought
forth bread and wine: and he was the priest of the most high God.
Later in John's writing we see Jesus saying that he is the bread of life... and we all know that the wine is the new covenant, in His blood. All this takes place in Cana, aka "The promised land". The same place God promised Abraham that he would be the father of many nations.
There is much more we could say about this.
Plus, isn't it bad for your liver? Or maybe that's just beer.
