Where did the devil come from?
He was formerly the highest-ranking angel in heavenāLucifer.
Isaiah 14 and Ezekiel 28 tell us that Satan was perfect in his original creation and that he was the ācovering cherubā over the throne of God, reflecting His glory. He walked in the garden of God and then fell into sin. Isaiah describes his fall from heaven through his five āI willsā that culminated in the heart of his iniquity: āI will be like the Most Highā (Isaiah 14:12-14). Jesus himself acknowledged this fall when He said: āI saw Satan fall like lightning from heavenā (Luke 10:18). Satan was thrown out of heaven because of pride. Because pride competes with God for control and glory, it is, therefore, the root of all sin.
