ok..
Thats probably because the judaism (the old testament) is not speaking about heaven at all... this is something that was added later
Anyway it really doesnt matter, because basicly the guy took judaism and said "you are praying the god in the wrong way" or something like did, he didnt tell them that the god they believed in was something else, he didnt tell them to change the way they are praying, or anything else.
i dont want to argue about this anymore, i said my point : christianity is somewhat upgraded judaism, which was supposed to stay as judaism but somehow turned out to be a new religion
