The name of a person is not a label. The name a person has says something about character and personality. The name of God, is not just a Handle. To know a name is to enable a relationship. Common knowledge of a name allows us to speak to one another and interact with one another.
Names are the beginning of relationships.
God wants to have a wonderful relationship with you, but that is almost impossible if you misuse God's name. And if we misuse or misrepresent God to others, we are bringing harm on God's name. Sometime back I saw a person with a FISH symbol on their car. The symbol told me they were supposed to be Christians. They drove like maniacs.
