“Are you saying that Judaism is no better than Christianity or Islam?”
You are missing something fundamental about Jewish belief.
Jewish theology states that the afterlife is available to everyone of any faith provided they adhere to the seven Noahide laws.
Jews, either by birth or conversion, have a much heavier load of requisite behavior to qualify - adherence to the Torah.
Judaism is totally different than the theology of Christianity or Islam which damns outsiders who do not believe and conform.
