John 2:1-10 "And the third day there was a marriage in Cana of Galilee; .... His mother saith unto the servants, Whatsoever he saith unto you, do it. And there were set there six waterpots of stone, after the manner of the purifying of the Jews, containing two or three firkins apiece. Jesus saith unto them, Fill the waterpots with water. And they filled them up to the brim. And he saith unto them, Draw out now, and bear unto the governor of the feast. And they bare it. When the ruler of the feast had tasted the water that was made wine, and knew not whence it was: (but the servants which drew the water knew;) the governor of the feast called the bridegroom, And saith unto him, Every man at the beginning doth set forth good wine; and when men have well drunk, then that which is worse: but thou hast kept the good wine until now."
The miracle's primary interpretation is to show that the new wine of Christ is: far better, and is the fulfillment of, the old wine of the Ceremonial Law undergirding Judaism at that time.
But there is another aspect of this story that gives insight into Christ's ministry that is critical and a part of a meta-interpretive understanding built up across several other accounts: 'Christ came to save sinners and make a people for himself from every tribe and nation'. Christ came to save sinners who knew their unworthiness, and whom the Watchmen were neglecting, and to do so from all the peoples of the world.
In this first miracle we see a group of such: the servants. They don't have names. We know nothing about them. They may not even have been Jews. They were tasked with such menial labors as filling the ritual washing pots. Probably also tasked in emptying pots of a more odious purpose.
These servants were the only ones to actually know the whole story. The governor of the wedding knew only that good wine was served. The bridegroom was happily surprised that the governor was happy, but uninformed by the particulars. Its not even certain that Mary knew what happened. But the servants knew. They knew that Jesus took plain washing water from a washing pot and transformed it into wine. Not just wine, but noticeably good wine. This may not even have been clean water, and it certainly didn't come from a pot used for potable purposes.
The servants took the water to the governor at Jesus' command. Did they know it was good wine when they took it? Were they being setup for a big joke and possibly punishment for impertinence? Imagine what would happen to these slaves if the wedding party knew that common unclean wash water was served to them. For the servants this was no idle command, and under normal circumstances would have been dangerous.
The servants obeyed Jesus. And as their reward they were the first to know of His divinity having witnessed this miracle. Jesus made it plain and clear - he ruled nature. And he blessed these nameless neglected servants with this testimony in a way they could not miss and could not forget.
Like Christ's testimony to the loose woman of Samaria who may have been the first that Jesus plainly told that he was the Messiah. These servants were the first to experience the desired blessing of Matthew 13:17:
"For verily I say unto you, That many prophets and righteous men have desired to see those things which ye see, and have not seen them; and to hear those things which ye hear, and have not heard them."
