The Third-commandment... why the Lord would be upset about mis-use of his name.

"Thou shalt not use the name of the Lord thy God in vain." Exodus 20:7

    In today's meaning of the word "vain" it holds two-meainings in the modern-dictionary: one meaning is having an over-inflated opinion of one's self, and the other meaning simply means useless or void, with no result. For the sake of this blog, I will go with the latter of the two-defintions, though I'm unsure of what the interpretation of vain was in the times of Moses. Though I was not around in the days of Moses and the establishment of God's holy law, I can only imagine their were several Jews and Gentiles, alike, that were using God's name for other purposes than to call upon him; maybe the word God in those days, much like today, was a verb or an adjective to proceed an obscenity, or maybe some people just had a strange-fetish for saying the name, God. Another reason might be because there were several Jews in those days creating graven-images, and worshipping the image as it was a god. Here is the thing though, unlike the images made of gold, stone or wood, the real GOD is the only existing god, and his name has power, if you don't believe me, just take a look at how many spirits were cast out in the name of God or Jesus. I mentioned that the name of "God" or "Jesus" has power to them; though these beings might not be physically-manifefsted in front of us, that doesn't mean that God won't make himself known whenever his name is incited; remember the movie, "Forrest Gump"? Lieutenant Dan thought he would mock God by his words, and "right then, God showed-up." This is a silly movie, but through prayer and the use of his holy name, God will show up in our lives. The point I am making is that I think God wanted his name reserved for when people needed him, and not to have his name of power, subjected to another useless part of speech. Unlike man, who is made from dust, God's name (God, Jesus Christ, and Holy Spirit) is powerful, and no other name under the sun has power in it, that is why we must make serious-inquiry when saying that name. A poor example to further my narrative is this: assume that someone calls the Police just to call them; there is no reason for calling them, but nevertheless, they will show up at your house, and demand an explanation for your call. I use a worldly examply like the Police because they have power on this planet, and certain authority, and if you call on the name of the Police for no reason, there will be consequences. Though this is a poor example, it still, somewhat touches the point. God expects his name to be used for serious-inquiries, and not to be used for "vain" purposes. God is the only name that has power to it. This is all just speculation, and may not be accurate, but its what came to my mind.
