The miracle of changing water into wine illustrates creation involving Father (the giver of the miracle) and Son (the implementer if it) - the Father designs and commands the work of creating and the Son implements the Father's will obeying the Father's commands by speaking and others obey the voice of the Son (like the servants were told by Mary "Whatever He says to you do it") and nature itself too obeys the commands of the Son because the Son always obeys the commands of the Father and believes the Father. Authority to create and govern creation starts with God and always goes through the name of the Son. I believe the Son even if not doing all the inplementing nevertheless it is in His authority and name that others including angels do it. So all is through the Son, even when the Son was flesh - while flesh and absent from heaven still ongoing governance and creating was being done in heaven by His authority - in His name. The water into wine miracle and other miracles demonstrate all this for us to believe. "Believe on the evidence of the miracles", He tells His disciples.
