How is the relationship between people who had open experiences with God or with his manifestations in relation to those who had nothing? Will God treat them differently when it comes to their behavior here on Earth? Will those who have had no direct or close contact with the divine presence have any compensation for moral failings compared to those they have? The Rambam says that only those who kept the seven laws of Noah will have the right to the world to come out of the conviction that it was a divine ordinance through Moses who wrote these commandments, how does he expect this to happen? The faith? Isn't this a foreign concept to Judaism being closer to Christianity? Does Judaism not stand on solid foundations of events? I consider Christian-type faith something very abstract and even dangerous if it involves concepts like salvation, wouldn't that be playing with people's destiny? Are those isolated people without any contact or concepts of Judaism, Noahide laws but somehow culturally observed all the noetic laws, are they lost by only considering them basic moral laws? Does Judaism somehow support that Pauline concept that those ignorant of the truths of Scripture will not be condemned?
In short. What is necessary for humanity to reach the state of consciousness that these universal moral commandments are the result of a will of a certain God since there are several "gods" out there. And what will happen to the people who observed these commandments in their own cultural consciences spiritually speaking?
