I always have felt that using God's name was disrespectful. We have many types of people that demand respect, such as teachers, judges, law enforcement, etc. We call them sir, Mr., Your Honor, etc. We would never go into a courtroom and address the judge by his first name. Therefore, how the hell do the witnesses get off calling God by his name? Whether that is the correct pronounciation is not my point. I just believe calling him by His name is just plain disrespectful. I will not do so again. There are many other ways to address Him that show dignity.
I would just prefer to error on the side of respect.
