The Private Miracle

I would entitle the changing of the water to wine the private miracle.

Kostenberger says it like this: the entire event served as a foil for Jesus revelation that his "time had not yet come" (2:4; cf. later 7:30, 8:20; and the arrival of the "hour in 12:23, 27, 13:1; 17:1) Nevertheless, Jesus finds a way not to "blow his cover": he performs a miracle "behind the scenes," without stealing the spotlight that properly belonged to the bride and groom, selflessly meeting the need of the hour.
