Once you have got past my hang-up about using a hyphen instead of an o, if I say "G-d", do you picture an old man with a long white beard, slinging thunderbolts?
That is not the Jewish idea of G-d.
Don't look so disappointed.
I once heard a rav of my acquaintance speak of "the Eternal".
That gives a better idea of the Jewish idea of the Eternal than the word "G-d" does.
Once you say "G-d", people think you are talking about the subject of Christian radio shows, and then it is all over.
Most Jews I know do not talk about "G-d" except when they are trying to translate themselves for people who don't speak Hebrew. In Torah texts, the Eternal goes by many different names -- names with the emphasis on love, on justice, on our relationship, on our responsibilities, "Ancient One", "the Place".
For the record -- all phrased in the negative since the precise identity of the Eternal is beyond what our minds can handle - G-d, in the Jewish concept, is not a person, male, female, narrow-minded, Christian, physical, Zeus, Iluvatar, hydrogen, strings, trees, machinery, outer space, light, out-to-get-you, Hallmarky, evil, or a fusspot.
