In addition, the reference is always to the God of Judaism and Christianity – never to the gods of other religions. Why?
If a person is an atheist, then taking the precious name of our God in vain is a blatant insult to both Jews and Christians.
If the person is a believer in God, as above defined, then using His name in vain is blasphemy and a direct insult to God himself. Why do people do this?
Incidentally, taking God’s name in this way does not prove that the speaker is clever, smart, wise, learned or erudite.
On the contrary, it proves they are the opposite of those. It also shows a lack of reverence for God and utter contempt for His people, as well as a deficient grasp of language.
Please desist and if you must attempt to dramatise language, improve your vocabulary to accommodate this.
