Yes it does! In Psalm 7:17 says, “I will praise the Lord according to his righteousness: and will sing praise to the name of the Lord most high.” (Luke 11:2). There are so many other scriptures that tell us to honor God’s Name and Who He is.

Jesus taught us this prayer through His disciples and we should be asking that God reveal His glory through His name in this earth. The OT patriarch honored God’s name as well as who He was.  This is giving God the glory He deserve.

I like that word “boast!”

Yes, and yes again!!  Personally speaking, I know He does. God has showed Himself to be the One and only true God in this universe. Since God changed my life there has been awesome things happen to help me know that God deserve the glory, honor, and all the praise. AMEN.
8).    Why does the Lord’s Prayer contain this phrase?

In the Lord’s Prayer, the phrase, “Hallowed be Your name” is appropriate, because not only is God holy, but His name is holy too.

The Lord took the initiative to pull us out of our former lifestyles. He saved us, cleansed us, and set us apart for righteousness.

We are holy because of Jesus Christ. We must live a holy life as well.
