Ditto what everyone else said. I too always found it 'uncomfortable' referrring to my 'Heavenly Father' by (what I believed to be) his Name...if I called my Earthly Father by name, I'd have got a slap, lol.
As I understand, Jews do not attempt to pronounce the Tetragrammaton for fear of blasphemy, as the correct pronounciation has been lost. The name 'Jehovah' was invented in 1270 by a CATHOLIC monk, Raymundus Martini.
