and said to him, "Everyone serves the good wine first, and when the guests have drunk freely, then that which is worse. You have kept the good wine until now!"
Thou hast kept the good wine until now ... This is the converse of the proposition stated above.  The contrast between the way God does things and the performance of people apart from God is dramatically stated.  With sinful men, it is ever "afterward, that which is worse"; but with God in Christ it is ever "the best wine last!"  This truth also has a wide application.
