Just a point like Metatron's above, on use by Jesus of God's name.
The JW's always go on about how Jesus was supposed to have made God's name known.
Yet when the disciples come to him and say "Teach us to pray" here is a good chance for him to put this into practice and use the name Jehovah.
So what does he do instead of starting the prayer, " Jehovah, our father in heaven, hallowed be your name." he decides to start with "Our Father in heaven, hallowed be your name." . To me this was one of the biggest chances of making the name "Jehovah" known but Jesus decides not to. So if Jesus thought that not using the name Jehovah, in a prayer he was using to teach how to pray, wasn't important. Why do the JW's seem to think it is.
