This beginning of signs Jesus did in Cana of Galilee, and manifested his glory; and his disciples believed in him.
An oriental marriage can certainly not be compared with our wedding feasts, as far as the duration and the number of guests are concerned. In the Galilean village of Cana the wedding was in full swing when the supply of wine ran out. Jesus was one of the guests, and His mother told him of the embarrassing situation. At first the Son of God did not respond. He took orders solely from His heavenly Father, not even from His mother.
Until then Jesus had rarely appeared in public, so that few had any idea of who He really was. Unexpectedly, the Lord gave orders for the six large waterpots to be filled with water, which undoubtedly took some time to fulfil. Some 500 to 600 litres of water had to be brought there, a huge quantity. Then the Lord ordered a sample from the waterpots be taken for the master of the feast to taste, a sample of the water that had inexplicably turned to wine.
The man was impressed by the quality of the new wine, of whose origin he was unaware. He informed the bride-groom how disconcerted he was that he had withheld the good wine, as he thought, for so long. It was an involuntary testimony of the miracle of the wine, as it is called.
Holy Scripture, however, designates it as a “sign”, a sign of the glory of Jesus, the Son of God. This sign, together with the message that Jesus preached, was so convincing that many believed in Him. We can do so today as well, on the ground of the reliable testimony of the Bible.
