"Thou shalt not take The Name of The Lord thy God in vain; for The Lord will not hold him guiltless that taketh His Name in vain." (Exodus 20:7)
"My Name continually every day is blasphemed" (Isaiah 52:5 )
"they blaspheme that worthy Name by the which ye are called" (James 2:7)
The story is told about a missionary in the Orient who witnessed a twenty year old native of that land, go up and bow before an idol, then he took a knife and cut his tongue out of his mouth and put it before the idol and right after that, he died at the idols feet, surrounded by his own blood.
The Almighty God does want us to cut our tongues out of our mouths, but He does want it to be set apart for Him. There maybe someone who does not care for Billy Graham or for the Pope but I am willing to bet money that, their names are not used in a disrespectful way. Because we respect them and honor them because of WHO they represent. These men are not to be reverenced but the One whom they represent is to be. I am sure that if anyone heard someone "damn" Billy Graham or the Pope, the nation would be in an uproar, but we are not in an uproar over the disrespectful way the name of the Lord is use. I am sure each of these men will tell you that they would rather for you to have respect for God, rather than for themselves, because it is God who is Holy and it is God who is sanctifying them each day.
The Jews had so much respect for the name of God that they made it a tradition not to even utter His name, but they substituted it for the name Adonai. They has so much respect and reverence for the name of God, that they put a hedge of protection to keep them from using His name in vain.
My personal feeling is, that of all of the profanity that is used, the word God damn is the worst of all, because you do not have the authority to make God damn anyone to hell. He sent Jesus to keep sinners out of hell and it is by their choice that they are damned to hell. The bible say that hell was created for Satan and the demons. Man through his disobedience chooses to go there.
There are many glorious names that the bible tells us that God can be called, and God damn is not one of them. We do not have to be like the Jewish people of old who would not utter the name of God for fear of using it in vain. God loves when we call out His name. This shows our need for Him and our realization that He does not want to damn anyone.
Try this one on for size the next time you are tempted to use God's name in a profane way, remember that He is Sovereign and He, not you have the authority of damning anyone.
God's Last Name is Not God Damn, but for your rejection of Him, He can Damn you to Hell.
