He was and is the covering angel. The Father has not taken his promise from him, but from all who followed him. But air is the symbol of spirit. He is the angel of spirit. He thought this would make him like the most high God. For his rebellion he was cast from heaven. He still is the angel of spirit but he can only offer death. Christ has power over life. He came to save those who could be saved. Only through Christ can we overcome death. Satan is not the angel of light. Regardless of what illuminists would have you believe. When he and all who followed him were cast from heaven, they're place in heaven is found no more. They are no longer of the light. Death and darkness is all he has. He seeks to weaken the body by deceiving many. His synagogue is alive and well, yet hidden. So be not deceived.
