God's name as it is written in Scripture is either Jehovah or Yahweh, or just YHWH. All are translations of He is Who He is. Because the Jewish people did not call God by the name he gave Moses.
It is for this reason that the Jewish people were so angry when Jesus said that before Abraham came to be I AM. To say God's name was to blaspheme.
For the people of Moses' time, names had power. They felt that to use the name of God was to say that they had power over God, and so the name was sacred.
I can remember an uncle of mine who would often take not just the Lord's name in vain when he was angry, but would also use it to curse whoever he was angry with. I'm sure you know many people who do the same without even blinking an eye.
Good Christians, all, who would be horrified if they were called on it. We are offended when people use foul language, why are we not offended when the Lord's name is taken in vain?
A friend of mine used to work in the office of a major manufacturing company and the man who sat behind her was continually cursing the company and its managers. One day she had had enough and turned to him and said, "No wonder the company is going to pot, you keep asking God to damn it."
He had never considered that he was both swearing and cursing, but he stopped.
What about us? Do we need to clean up our speech, or ask other to do so?
