God's use of language

The commandment, "Thou shalt not take the name of your Lord God in vain" has always seemed one of the lesser of the Ten Commandments, to me. God wanted proper respect for his name, sure, but didn't he also elevate us to the level of co-heirs with him in his kingdom?
A few class periods ago, my worldview professor explored God's use of language.

• God created the world by speaking it all into existence.
• Jesus used language to perform his miracles. He spoke to the storm while the disciples cowered in fear. "Be still!" he said and the storm ceased.
• Jesus, on another occasion, verbally cursed a fig plant and it withered and died.
• God revels himself to us today by the Bible--the Word of God.

Somehow, there is this power contained within language itself. Although we use a language which is as broken as ourselves, there is a remnant of power within it.

• Paul writes that "because, if you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved." (Rom. 10:9)
• "I tell you the truth, if you have faith as small as a mustard seed, you can say to this mountain, 'Move from here to there' and it will move." (Matt 17:20)
• Adam's calling in the garden was to classify and name the animals.

I don't know what the implications for this ideas is yet. I don't know how it will change my writing or how it will affect my everyday speech. But it does explain why God is so concerned with the use of him name.
