Steve Sensenig has a really good post called "More Than Meets the Eye" on his blog today. It's on using God's name in vain.
Some of the discussion and subsequent comments dealt with the unwillingness of the OT Jews to even speak (or spell) His name, and the reasons behind that action. The people of the past weren't the only ones who felt that way. If you read the Israeli newspapers today, you will find that they avoid the use of His name or spell it "G-d".
As I thought about the many times in a day that I hear the name of God used, I was reminded that profanity and slang are not the only offenses. How often have you talked with other believers and they assured you that "God said....", or "God wants..."? How many times have you chuckled at a joke or cartoon that used His name irreverantly? How many times have you done it yourself? I have, and I need to be reminded often Whose Name I'm throwing around so casually.
What about our promiscuous use of the word "Christian" as an adjective showing God's endorsement of everything from weight plans to fantasy fictional romance to t-shirts. His name is showing up on things that must disgust Him. We have made the Sovereign Creator and Ruler of the Universe into just another household commodity!
Why doesn't that disgust us?
