I Am Who I Am communicated with faithful prophets in order to create a faithful world. The Holy Books tell the stories of the interaction between I Am Who I Am and the prophets. The stories in the Holy Books show for instance aspects of Paradise and Heaven. Many cultures, religions and philosophies contributed to the purpose of I Am Who I Am for a honest world.
The Honest World is a human world in which every human knows the boundaries to the other human being. Honesty is not in the word alone, it is in the interacting on any level with other human beings. I Am Who I Am gave Commands not to do when interacting with other humans. Do not kill, do not steal, do not abuse, do not lie, do not enslave.
The Command not to make idols and not to make a picture of spiritual beings like God or angels are given for the interaction of humans with The One, with God.
Then and today there is too much fantasy about the spiritual world. There is no devil, there are no angels, there is no original sin. There is no resurrection from the dead. It is humanity that brings death, ignorance and dishonesty. Warlords are the devil. Mankind makes hell. The fantasies are made by people who think they are god, they glorify sins and make the people suffer in fear and uncertainty.
Angels are a manifestation of The One, which people see with their spirit and who are given a name by humans. From birth God gives a clean spirit (soul, mind and heart), there is no original sin.
