There are many verses in the Bible telling us that we should honor God's name. Exodus 20:7 & Deuteronomy 5:11 are two familiar examples. In most translations, these verses are identical in both books.
"Thou shalt not take the name of the Lord, thy God, in vain...." (KJV)
"You shall not misuse the name of the Lord your God...." (NIV)
I especially like the way the MSG & VOICE translations render these verses.
"No using the name of God, your God, in curses or silly banter...." (MSG)
"You are to not use My name lightly or flippantly or as a curse...." (VOICE)
My spirit, in fact my entire being cringes when I hear someone doing this. I'm sure we have all heard people saying things like ...
"Oh my God, look at that cute outfit!"
"Will you go clean up your room, for Christ's sake?"
"What in God's name are you doing?"
"For the love of God, get in here!"
I remember watching The Weather Channel one day while they were showing a home video someone took of a funnel cloud heading toward their neighborhood. Someone ... either the person filming the video or a person nearby ... kept saying over & over again, "Oh my God! Oh my God! Oh my God!" I don't think I can adequately explain how grieved I was at this.
Did you know that there are words that people use in place of God's name but they are still the same? I first was made aware of this when I was in 7th grade. I attended a catholic grade school (grades 1-8) & one day I was standing with some friends & one of us said something like "Geez, will you look at that!" One of the nuns at the school happened to hear this as she was passing by & she really laid into us for using Jesus' name like that. It never occurred to my friends & I that "geez" was just a shortened form of Jesus ... a "polite" way to dishonor God's name. At the time we all thought that nun was crazy, but of course with age comes wisdom (hopefully). Geez, gee, gosh, golly, egad, "oh my goodness," Jiminy Crickets, & similar words & expressions are all "polite substitutes" for God's name.
If you love God, if He is important in your life, if you want to honor Him at all times, listen to the words you say & to take a good look at the things you write. If you discover that you are dishonoring God by using His name "lightly or flippantly or as a curse," pray for His help to stop. In Psalm 141, the psalmist asks God to "set a guard over my mouth." I ask God to do this for me every day. I encourage you to ask Him to do this for you as well : )
