God has built into the universe, laws, the regularities we observe. However, these laws don't prevent him from intervening, if he chooses to create an irregularity which we call a miracle. Jesus performed his first miracle at a wedding in the small village of Cana in Galilee, when he turned water into wine. He did this for a bigger purpose than simply resolving an embarrassed bridegroom's dilemma. This miracle in John's Gospel is the first of the 7 signs revealing Jesus' true identity.
