I'm sorry you feel that way, I do notl feel that asking the question about the original Hebrew name of Jesus to be inappropriate on a Christian forum, and yes it matters to me a great deal as does plenty of others who choose to use a different name than Jesus, that is closer to his original name. The Bible states that every knee should bow, in heaven and on earth and under the earth (Phil 2:10) so I feel it would be proper to know that name in its authentic form.
I personally feel that after praying about it, the answer gets revealed.
I don't quite know what you mean by, What spirit am I doing it in?
I would of thought it was obvious

I take it you know there is a thread on God's name in the forum?
They are important threads.
