The ancient Hebrew scribes refused to speak the name of the LORD when they encountered it in the Old Testament text. Instead they would say, "Adoni," which is, "my Lord." Those same vowels (in Hebrew) became the vowels in the Lord's name when the Masorites pointed the text (put vowels in a voweless bible); thus, YAHWEH (it works, trust me).
When scribes went to write the NAME, they wrote it and then broke their stylus (writing utensil) in half. The stylus was holy. You shall not profane the Name of the Lord your God. This simple act kept before them the awesome terror of what they were doing. They revered and feared the Lord and so treated His name has holy.
I was just typing and accidently wrote "Gof." Sure, the "F" key is right next to the "D" key. And sure, the designation "God" is derived from the germanic tribes reached by the first Roman missionaries and has no inherent holiness as a word. Yet, that simple mistype sent a shudder through my heart. We are so careless with the name of the Lord. God, gosh, Jeeze, and further, more profane designations, pepper the vernacular. But I don't care to bemoan that old complaint. I want to draw your attention to the frivolity with which we write and type words that refer to the God of all the world. We must not take the Lord's Name in vain. We must not treat the Lord of glory with contempt by hurrying past Him in order to prepare our lessons, type our blogs, reply to our emails. We must revere the name of the Lord, to keep it holy. The keys of this keyboard stick. I've misspelled the Lord's Name several times in this posting. Lord, forgive me. Keep Him holy, friends. There is no one like Him, and He is jealous for His Name's sake.
