Have you ever noticed that people who claim to have no animosity towards the Living God use His name in a flippant manner.
Blasphemy has been long overlooked as an excellent proof for the truth of Christianity.
The world around, you can find people who find weird and imaginative ways to curse God. My friend Taketo is Japanese and speaks very little English. He was speaking to a friend in fluent Japanese and I was simply listening with interest, when I heard a derivative of, "Christ" in the middle of his conversation. Taketo, a Buddhist, chose to blaspheme the God of the Universe instead of the god of his culture.
If you ask a secular person for an example of Blasphemy, you'll usually hear "Goddammit", and this is certainly one of the worst. But it is not the only. "Jesus Christ" used without reverence is another example, but so are the ones most people don't think of. "Geez" is blasphemy, without any effort whatsoever you can see that its etymology derives from "Jeezus". Other examples are simply the acronym OMG or the phrase, "Oh my Word" (John 1:1), and especially "Oh my Gosh". If Gosh is not a derivative of God, then I ask you what Heck is a derivative of?
"Man" can be blasphemous of "Son of Man" and similarly "Man Alive" is blaspheming the same name of God. "Word up" was popular a few years ago, and you should now see the blasphemous reason it caught on. Similarly, “Good Lord”, “Oh my Goodness”, and “Goodness Gracious” are all blasphemous.
Perhaps the worst one is "Son of a B..." and other “Son of a” phrases. These are certainly not accidents in language, but cursing Christ through His mother and Father. You are also implying a less than ideal name for Jesus Christ through lineage.
I'm certain I haven't given you even a taste of the curse words that have been invented to curse the Living God, but you see the point.
But why does it matter? The Bible says that God's name is the only name blessed forever. When you curse it, you are declaring your hatred for God by trying to drag His name into the mud. Notice that no-one ever yells out, "Siddhartha Buddha" when they hit their thumb with a hammer, or says, "Allah dammit." The reason is because these names are already cursed. But not the names’ of God, of these Jesus Christ is the name above every name.
Be assured that you don’t need to speak in order to blaspheme God’s name. You are created in the image of Him and of His name. In this you reflect Him and the world can see Him in you. In a perfect world, this would be a wonderful honor, but unfortunately it is also an opportunity for blasphemy.
When you tell a lie, then you tell the world that God is a liar. When you steal, the world doesn't just see you, but an image of God, and determines that He must be a thief. When you speak idle words, you tell the world that God's Word is not eternally important and omniscient. Out of the mouth the heart professes, when you speak curse words you tell the world that God's heart is not infinitely pure. When you look at someone that is not your spouse with lust, you commit adultery in your heart, and you tell the world that the covenant God has made with His bride, the church, is not binding and is not trustworthy.
Another form of blasphemy is when you raise other religions to the level of God, by doing this, you insult His sovereignty, justice, and mercy. Holy Cow is derived from Hinduism and the debacle of the Israelites at the base of Mount Sinai. When you say that the God of Christianity is the same god as Islam, you insinuate that the Living God is unjust, bribable, inhuman, and unloving. When you fixate on one attribute of God, you present an imperfect view of Him. God is Love, but He is also the Righteous Judge, who is Angry with the wicked everyday, a Consuming Fire, a Strong Refuge, an Everlasting Rock, Holy, Mighty, Merciful, Gracious, and the God of Salvation who by no means will clear the guilty.
God will not hold him guiltless that takes His name in vain.
Even in the hundreds, if not thousands, of times you have blasphemed God's name, He still loved you and gave Himself for you. Jesus Christ, God the Son, came to this earth, born of a virgin, lived a perfect sinless life, offered Himself up to be crucified on the charge of claiming to be God, died in your place, and on the third day defeated death and rose from the grave. If you'll repent of all your wicked ways, especially your habit of substituting His precious name in place of your filth words, and place your trust in Him, He will save you based on His atoning payment on the cross and forgive you in spite of your hatred of Him. Once you have done this, He will replace your heart with a heart that thirsts for righteousness and loves Him.
Finally, if you hear this message and decide that this offer is not reasonable, that you’d rather hang onto your blasphemy and sundry sins than submit to God, whose name is Righteous, then you commit the sin of blasphemy against the Holy Spirit and this sin will not be forgiven. Today is the day of salvation, call out to God in repentance and faith, and all of your sins will be forgiven of you.
