The First Miracle of Jesus Christ
Soon after the first disciples were called by the Saviour, in the city of Cana, not far from Nazareth, there was a wedding. To this wedding were invited Jesus Christ with His Most-pure Mother and the disciples. When it came time for the wedding banquet, there was insufficient wine. The Mother of God noticed it and said to Jesus Christ, "They have no wine."
But Jesus answered, "My hour is not yet come."
From this answer, the Holy Virgin understood that the time had not yet come for Him to reveal His divine power, but She knew of the love of Her Son for the people and was sure that He certainly would help the needy; and, therefore, She said to the servants, "Whatsoever He saith unto you, do it."
In the house, there were six large water pots of stone for purification of water, after the manner of the Jews. Jesus Christ ordered to fill the water pots with water. When they were filled to the brim, He said to the servants, "Draw out now and bear to the governor of the feast."
The servants drew and bare it to the governor. The ruler of the feast tried it and saw it was the very best wine. Then, he called the bridegroom and said, "Every man at the beginning doth set forth good wine, then that which is worse, but thou hast kept the good wine until now." The governor said this because he did not know from whence the wine came. Only the servants, who drew the water, knew.
Thus the Saviour began His miracles and revealed His glory, and His disciples believed in Him.
The first miracle of Jesus Christ was accomplished on the request of His Mother. From this, we can see that Her prayers for us have great power.
