If the name of God and His Son are so important to the faith, then would it not be imperative that we use the proper name?

In order to appropriately answer the question, in my opinion there are few things to consider. First, there are those that have argued that the pronunciation of the name is not important and is permissible to be used in any language. However, if the LORD gave His name and pronounced His Name and at the sound of that name every knee shall bow and every tongue shall confess that _________ is Lord, then wouldn't it make sense that the name and pronunciation of the name be the same? I have been in countries where the language is not mine own but my name was pronounced in my native language, so it just make sense for us to do the same to be on one accord. Secondly, if it is the **name** that saves, casts out demons, heals the sick, raises the dead and expels demons and makes them tremble, shouldn't we spend time getting it right?
