The wonderful Rabbi Sacks says it all.
Incidentally, the line "aval zeh shelanu", is Hebrew for "but this is ours" is a line from his book, wherein he describes an encounter with an Israeli Jewish skipper on a boat on the Galilee, while he and his wife were on vacation. The conversation was something about how beautiful England was, or something like that and then the skipper looks about the Sea of Galilee and the beautiful Golan Heights looking over Tiberias, and said 'ahh, but this, this is ours'.
I remember that line from the book very acutely.
This is my faith. This is also why I am a Jew. This is very moving.
