I'll tell you what name the JWs like to emphasize. I was at a meeting this week and the dude Elder who opened with prayer repeated the term/name 'Jehovah'...must of been 15 times...from beginning to end he would begin a sentence with 'Jehovah' and end the same sentence with 'Jehovah'. It went something like this:
"Dear Jehovah bless our meeting today Jehovah! And please Jehovah may your Holy Spirit be with all those who have a part tonight Jehovah"...on and on and on!
Then the dude Ministerial Servant got up to close the meeting with prayer...it was similar like this:
"Thank you Jehovah for the spiritual feast we had tonight Jehovah. And Jehovah please watch over us Jehovah as we each go our separate way to our homes Jehovah"...on and on and on...I think he mentioned the name/term some 11/12 times in his prayer!
Personally...I think God Almighty tunes-out these type of juvenile/immature prayers!
The question and answer sessions were very similar in nature. Each and every JW member when giving an answer would start their sentence with Jehovah and end the sentence with Jehovah. So if their comment consisted of 5 sentences they would of mentioned the term 6 to 8 times...silly!
