Abdiel is the only seraph who remains loyal to God in Paradise Lost. He is a symbol of fidelity and obedience, and he serves as a foil to Satan, who is the epitome of rebellion and pride. Abdiel's loyalty is tested when Satan tries to persuade him to join his rebellion against God. Abdiel refuses, and he argues that it is better to obey God than to follow Satan. He also warns Satan that he will be punished for his rebellion.
Abdiel's loyalty is rewarded when God sends him to Earth to protect Adam and Eve from Satan. Abdiel successfully defeats Satan, and he helps Adam and Eve to escape from Paradise. Abdiel's loyalty is a reminder that even in the face of great temptation, it is possible to remain faithful to God.
