miracle of water into wine symbolism

The water pots of stone were used for the purification or cleansing of the Jews. Christ turned the water to wine. Wine is symbolic of Christ's blood- there are scriptural references, sacrament, etc. The only way we truly become purified is through Christ's atonement. Just as they took into their bodies the wine we must take into our hearts and lives the Atonement so we can be cleansed and purified.
