At Your Name (Yahweh, Yahweh)

Is it just me, or does it seem like people are afraid to call God by his real name? In some religions it is considered a sin to speak the name of God, let alone write it out, but if my observation is correct, then why? I first heard At Your Name (Yahweh, Yahweh) at Phil Wickham's concert about a year ago, and since then this question has been rattling around the back of my mind.
This past July I went to Barranquilla, Colombia on a mission trip with E3 Partners and most defiantly had a heart transplant. There I met and saw so many people who were being moved by the spirit and love of God, that it made  me want to shout "Yahweh, Yahweh," There in Colombia I learned a lot from my dear friend Roberto. At the time I was telling him about the hunger for the gospel there in Colombia, and the rejection of the gospel in the United States, and how it was causing me not to want to go back to the US. He then asked me,
"What is your favorite food that your mom makes for you?"
I was a little disheartened at this random question, as I was naively having a bit of a pity party for myself, but despite this I replied with Sopa de Fideo.
"Who do you thank for making the meal?" He asked.
"My mom," I replied, still I was not sure where our conversation was going.
"Your mom was the chef, but was it not the pot who sat on the fire and heated your food?"
After a couple of seconds I responded with, "I suppose it was, but who wants to thank a pot?" 
He laughed and said, "Exactly, the pot compliments the love the chef makes the food with. This is how it is with God...

"... we are the pot, we sit over the fire and take the heat to prepare the food that God has given us so we may feed the people God bring to the table. In this we hope that the people will give thanks to God, not the pot."

When Roberto said this, inwardly, my jaw dropped. I had been a missionary for all of three days at the time, and had gone through a lot of training to do what I had been doing, but no one had explained it to me like that with such simplicity as a pot. After this analogy he then told me:
"God has placed you in the United States for a reason, just as he has placed me here, in Colombia. He has made you a good pot here, so what makes you think he will not help you to be a good pot in the United States?"
I did not exactly know what to say, so I said nothing, though I am sure my face said it all: Nothing. Nothing should make me think that he can not use me. Sam Ingrassia said that every moment on a mission trip can be described in two categories: Defining Moments and Divine Appointments. Divine Appointments are when you declare the gospel to a person that God put in front of you for a reason. A Defining Moment is a moment when God himself crosses your path. This was defiantly the most important Defining Moment for me on the trip. It made me realized that God can and will use anyone right where they are. Whether that is in their own home, school, work place, or maybe even half way across the world. He doesn't care who you are or what kind of crap you've done, because God doesn't call the qualified. He qualifies the Called. He shapes us and molds us slowly, day by day into beings who realize their imperfections and know that God loves them anyway, beings who rejoice that he uses us. Beings that love to shout his name, whether we shout "Yahweh," "God," or "Being I feel stirring inside me that I can't put a name to."
So even though I cried like a baby at the airport in Barranquilla, and even seriously considered running back to the Majestic Hotel, I got on the plane, confident that God would use me Anywhere. No matter if I was in Colombia or on an airplane ordering food from a flight attendant. And although I did slip into a little bit of depression after returning home, God did use me. And even in my sadness I wanted to shout "Yahweh, Yahweh!" with joy.
If we trust Him enough to get out of the way, God will mold us into beautiful pots that prepare food for the plenty.
