Lucifer was an angel in Heaven of course we know that. In Heaven he was the angel of music and when him and the other angels would do music beautiful colors would surround Lucifer and illuminate the surroundings. Some other angels were astounded by his beauty and chose to follow him, This gave Lucifer a big head thinking that he can be GOD and tried to take over. The devil, lucifer, satan whatever his name is (as if it matters) is of evil and our job is to worship GOD not and spread the truth around. What you should be focused on besides satans tru name is The second coming of CHRIST and getting your soul ready and spread as much of the Gospel as you can. GOD BLESS
