The book of revelation tells us how it all began(rev 12:7-9).one third of de angels of heaven followed this devil in his rebellion--(Rev 12:3,4).lucifer fell from his exalted position(isaiah 14:12-14),God did not destroy lucifer immediately;he is a God of love and did not want to be worshipped in fear by the unfallen angels.The battle began in heaven but has continued to the planet earti.Our planet has become a spectable to the world,both to angels and to men.Amen!!!
