After meeting with the first few disciples, Jesus and his disciples head of to Cana of Galilee after getting invited to a wedding that Jesus's mother also attended. One problem in the wedding -- the wine ran out.
In fact, Mary (the mother of Jesus) was the one to tell Jesus that the wine ran out. However, Jesus asked Mary why the concern has to do with Jesus and explained that his "hour has not yet come." (2:4) Seems to be an interesting response, so let's analyze it.
First off, some commentators noted that Jesus referred to Mary as "woman". In the Greek world (like in Iliad or as described in Interlinear notes), the phrase is indeed appropriate for use. Next, regarding the question on why the wine has to do with Jesus as well as timing, Jesus is essentially explaining that he sometimes works at a later time (he still does it, just not immediately).
There are a few ideas on why he chose to work a bit later. First off, Jesus is treated as a guest rather than a host, so aside from life-threatening issues, most of the structure of weddings is meant to be managed for the hosts (maybe a risk of interference weirdness). More important, Jesus's timing of his later fix is meant to be a sign that Jesus is who he says he is (miracles are his credentials in his life).
However, even with the delay and seemingly non-response, Mary still told the servants that they should do whatever Jesus says to them (2:5). From her initial request to ask Jesus (not to mention that she gave birth to Him), Mary knew that Jesus is meant to be a very important person. But without the immediate fix, Mary still knew that Jesus was important in solving the problem (likely from what she knew about Jesus)! That's trust right there, and Mary shows that we can trust Jesus in delays.
