Matthew 6:9 GNT This, then, is how you should pray: ‘Our Father in heaven: May your holy name be honored.'
Matthew 6:1 - 34
NLT - 1 “Watch out! Don’t do your good deeds publicly, to be admired by others, for you will lose the reward from your Father in heaven. 2 When you give to someone in need, don’t do as the hypocrites do - blowing trumpets in the synagogues and streets to call attention to their acts of charity! I tell you the truth, they have received all the reward they will ever get.

You can actually use it as he commands! His name is not "God," (that could be anybody!) His name is Yahweh and He commands that His name be praised among the nations. Hard to do that when you refuse to speak it! The reason you don't say it, is because the Jews refuse to say it, because, as Edomites, they worship Qos, Moloch, and Rephan, not Yahweh the God of Israelites!
