Take a clipboard out to the sidewalk and ask people this one simple question:
"Can you tell me who Jehovah is?"
If more than 1 in 4 say that it is God's name I would be SHOCKED. It's probably less than 1 in 10.
Even fewer would know who YHWH is.
I'm not arguing that USE of the name is CORRECT. I'm just arguing that if you are going to call God by the accepted cultural name, like it or not, Jehovah is still it. People just don't use the name "Yaweh."
