Dear Myrna,
Your scripture is a very nice one to help people understand the importance and holiness of God's name, which G-O-D or L-O-R-D is not a name, but are titles. Just like you have a name and people show you respect by using it, we should all show the Creator of the Universe the utmost respect by using His holy name, which is JEHOVAH! Jesus himself did so and told us in the model prayer found at Matthew chapter 6 when asked how we should pray that "hallowed by thy name." The word hallowed means holy, sacred. How can one show respect and treat that name as sacred when they never use it and, in fact, it has been stricken from their Bibles? This is Satan's work, for it was once in the Bible over 7,000 times!
Since your scripture is in Isaiah, go a little further and check out what God Himself said about His holy name at Isaiah 42:8:
"I am Jehovah. That is my name; and to no one else shall I give my own glory, neither my praise to graven images."
If people will read the book of Psalms, they will see hundreds of references with regard to the importance of Jehovah God's name and of praising it, proclaiming it, and using it. Here are just a couple of those:
Ps. 83:18, "That people may know that you, whose name is Jehovah, You alone are the Most High over all the earth."
Ps. 34:3, "O magnify Jehovah with me, YOU people, And let us exalt his name together."
Ps. 91:14, "Because on me he has set his affection, I shall also provide him with escape. I shall protect him because he has come to know my name."
Ps. 9:10, "And those knowing your name will trust in you, For you will certainly not leave those looking for you, O Jehovah."
Ps. 29:2, "Ascribe to Jehovah the glory of his name. Bow down to Jehovah in holy adornment."
Ps. 113:3, "From the rising of the sun until its setting Jehovah’s name is to be praised."
Here's a very important one in Ezekiel 39: 6 & 7:
"And I will send fire upon Ma´gog and upon those who are inhabiting the islands in security; and people will have to know that I am Jehovah. And my holy name I shall make known in the midst of my people Israel, and I shall no more let my holy name be profaned; and the nations will have to know that I am Jehovah, the Holy One in Israel."
I could take up pages upon pages here of scriptures from the Bible that has restored God's holy name to every place it once appeared, but just in closing may all take heed of what the Apostle Paul told us:
Romans 10:13, "For everyone who calls on the name of Jehovah will be saved."
Hebrews 6:10, "For God is not unrighteous so as to forget YOUR work and the love YOU showed for his name, in that YOU have ministered to the holy ones and continue ministering."
Lastly, Jesus himself also said regarding God's name, at John 17:6:
"I have made your name manifest to the men you gave me out of the world. They were yours, and you gave them to me, and they have observed your word."
I hope all of you will come to understand just how important it is in your relationship to Jehovah to use, proclaim and glorify His holy name!
