It’s not a matter of using one of G-d’s names. It’s a matter of misusing one of them: Using it in a situation where it is not appropriate. In prayer, for instance, names of G-d, (Yehovah, Elohim, El Shadai, El Elyon, etc.), are used just as my or your name is used in ordinary conversation. Prayer, for Jews, is conversation with G-d, not just asking for what we want, but also talking about what’s gone on or going on in our lives. Sort of like a We take verses like “Cast your burden on Yehovah, and He will sustain you” seriously. I guess the best way to put it is: For a Jew, prayer is intimacy with G-d. Anyone who has a significant other, or husband or wife, isn’t going to go around sharing all of the details of their relationship with others, and may even allow certain publicly known misinformation that, by today’s standards, casts one or both people in the relationship as prudish in order to protect the sacredness of the relationship. Just as certain petnames for your significant other are used only in certain situations, so we use the names of G-d fully only in certain situations. OK, this probably should have been a journal entry. LOL!
