Im just thinking about replacing every name for God with Jehovah.

Most translations use Lord because He is called the Lord of lords in Revelation, Deuteronomy, Psalm, and 1 Timothy.

In Exodus God calls Himself the I AM.

The prophecy to Mary from the angel said Jesus would be called Emmanuel

I believe that the Maker of everything, including language, can choose to have many names, so why is only the one used by JWs?
