Vidiot- I know what you mean about using the name Jehovah, I was never comfortable with it. I always thought there must be something wrong with me because other brothers and sisters would liberally pepper their conversations and prayers with "Jehovah this..Jehovah that..." as a sign of their superior spirituality.
There was even one sister who told me proudly "me and Jehovah are like that" as she made the entwined fingers sign for closeness.
I used to wonder why Jesus didn't use the name in the model prayer.
