Why did Jesus turn water into wine?  There was deep symbolism in what He did.  Can you see it?  First read it:

Now there were six stone water jars there for the Jewish rites of purification, each holding twenty or thirty gallons. Jesus said to the servants, “Fill the jars with water.” And they filled them up to the brim. And he said to them, “Now draw some out and take it to the master of the feast.” So they took it. When the master of the feast tasted the water now become wine, and did not know where it came from (though the servants who had drawn the water knew), the master of the feast called the bridegroom  (John 2:6—9)

OK – to figure this out, answer these questions:

1. What were the water jars used for?
2. Do religious rites of purification, the ceremony of washing really purify a person? 
3. When you wash with soap and water, is that done on the outside or the inside? (I know, dumb question, but it will make sense when you read the next one…)
4. Is wine taken inside or used outside a person’s body?
5. When used properly, what is the effect of wine?  Is it the outward appearance of cleanliness or the inward experience of joy?

Jesus met a real need; the wine had run out and He supplied more.  But He also gave a big, symbolic hint about what He had come to do.
