What is Lucifer?

Lucifer is Lucifer, which is Satan. I believe many people know that Satan is a devil, but they don't know that he was an angel, and his name in heaven is Lucifer. Satan means enemy, and Lucifer means morning star. The Bible says that Satan fell from a shining star. It appears as a male angel holding a torch. There are too many arguments about the reasons for Satan's fall. 1. Satan betrayed God because he was jealous that his twin brother Michael became an archangel instead of himself. 2. Satan is a perfect archangel in heaven, but he was indignant because God suddenly asked angels to obey not only its will, but also Jesus' will, so he called a third of the angels to fight against God. The reason is that "it is better to be the king of hell than the slave of heaven." God thinks: you, Lucifer, are the most perfect angel created by my God. Now you are arrogant and want to hold your throne higher than my God. This is betrayal, evil and clever evil! So he will be punished forever. Does this make people feel that this god is a bit unfair? The true creator should only love, not hate! Until the truth comes out.
