WARNING: POSSIBLE RANT AHEAD!
His mother said to the servants, "Whatever He says to you, do it." Now there were set there six waterpots of stone, according to the manner of purification of the Jews, containing twenty or thirty gallons apiece. Jesus said to them, "Fill the waterpots with water."And they filled them up to the brim. And He said to them, "Draw some out now, and take it to the master of the feast." And they took it. When the master of the feast had tasted the water that was made wine, and did not know where it came from (but the servants who had drawn the water knew), the master of the feast called the bridegroom. And he said to him, "Every man at the beginning sets out the good wine, and when the guests have well drunk, then the inferior. You have kept the good wine until now!" John 2:5-10
I refuse to enter the "can the Christian drink" debate. Many who wish to say that we cannot use take this passage to mean that Jesus turned water into grape juice (though that must have been some really amazing juice to get drunk off it...! cf v10).
Let's focus on the point of this miracle... Jesus bypassed the fruit. Whether you believe it was grape juice (again... really powerful, you can get drunk off it, grape juice) or wine, notice that Jesus didn't need grapes.
What is He telling you to do that seems like it can not be done because of some obstacle? Sometimes bypassing the process is the process.
I don't know what He is calling you to do but I do know that all of us should take His mother's advice:
Whatever He says to you, do it.
PS... Luke 7:34 says:
The Son of Man has come eating and drinking, and you say, 'Look, a glutton and a winebibber, a friend of tax collectors and sinners!' Ok... I'm done.
