I have always thought the JW fascination with the name of God to be odd and irrelevant.
How could it possibly matter one way or the other whether or not a person audibly produces the correct consonants and vowels associated with the Creator.
The significance of a name is only that it identifies a distinct person. It might carry the extra function of providing an attribute with which to identify the person.
But here is a question that highlights the absurdity of this fascination.
Suppose I speak the name Jehovah, and say I am serving him by murdering someone. Suppose another person speaks the name Lucifer, or Satan, or Devil, and claims to serve him by helping another in a way they would want to be helped.
Who does the first person serve? Who does the second person serve? Did the name they utter have any bearing on the answer to these questions?
