When someone wants to curse someone or something, they use the name of God and the word Damn and then list the desired person or thing. But wait a minute, what about the following verse from the book of Deuteronomy? Deu 5:11 "'You shall not take the name of the LORD your God in vain, for the LORD will not hold him guiltless who takes his name in vain. English Standard Version
A person's name represents that person; their appearance, character, and really everything about them. So, when someone curses, invoking the name of God they are taking HIM very lightly indeed. God is not to be ignored, trifled with or referred to without respect. So, this commandment goes way beyond speech because in fact it really permeates every aspect of our life. I like what Max T. Neel used to say:"God is closer than hands or feet and nearer than breathing". Because I accept that as truth, I know God is watching what I do and I need to be careful. Respect is respect, and a lack of it has consequences.
