Why are the Sacred names not used by this author? "Yahweh" our creator, "Yahshua" his son, our savior. The name revealed to Moses, used over 7,000 times in the Old Testament. What happened to the names?
"Yahweh" and "Jehovah" are really the same name. Hebrews used a short-hand form of writing that did not include vowels. So, it would literally read: "YHWH." The letters that are transliterated "Y" and "J" are actually very similar in the Hebrew language, so, at some point, someone translated the word "JHWH." The original name given to Moses in Exodus was Yahweh.
In Old Testament times, however, the Hebrews considered the name Yahweh to be so holy that they would not speak it. Instead, they replaced it with Edonai (Usually translated 'Adonai,' which means Lord. (In fact, the name Jehovah is a combination of JHWH and the vowels from Edonai....JeHoWaH).
These names have simply been translated into English. There is nothing wrong with this.
