Okay, that's great then. They knew He made an intoxicating beverage that contributed to their sin. Sure, that's a great testimony.
But you are missing the point. The wedding guests did not know that Jesus was going to contribute to their drunkenness (if what you say is true).
It seems to me that "Don't let it control you" went out the door when Jesus contributed to their drunkenness in secret at the Wedding party (if Jesus did indeed make intoxicating wine).
But if what you say is true, there should be NO verses about how strong drink is bad.
For Scriptures says it stings like an adder. Do not look at wine when it is red. Woe unto those who give their neighbor strong drink, etc.
