What the Bible says about Beginning of Signs
(From Forerunner Commentary)
The "beginning of signs Jesus did in Cana of Galilee" (John 2:11) tells us something of God's creative effort. In Cana, Christ turned water to wine. Mankind had an essential part of this miracle, for, at His command, those at the wedding feast "[f]ill[ed] the waterpots with water" (verse 7). Nevertheless, the miracle was God's, who works through Christ (John 5:19). Tasting the new wine, the master of the feast tells the bridegroom, "You have kept the good wine until now" (verse 10). The wine God created—with man's help—is better than the wine made by man alone.
