Today's gospel reading was about a wedding feast at Cana. Jesus, and his family, were in attendance. Now, as almost every Christian should know, the wine ran out and Jesus changed the water into wine.
It's a good story. The first miracle. Just to play devil's advocate, let's look at the water, the barrels, and the wine.
The barrels which held the water held 20 to 30 gallons. There were six such barrels. This made somewhere between 120 and 180 gallons of wine. Also, the Bible reads that this was "good wine." Jesus not only made a lot of wine, but he made a lot of "good" wine.
