I think that we hallow the name of Christ when we praise Him and worship Him. By hallowing his name we are reminded that he is the Holy One and sinless. We disrespect Him when we take his name in vain, ie: Lord, Jesus Christ, My God, and swear. We use so much of this in our daily language that it has unfortunately become a part of our language and we must strive to remember just who Jesus Christ is. When we begin to pray we can start with praising the names of God, like Jehovah, Shammah, Shalom, Nissi etc and then go in to how wonderful He is.
