Satan's expulsion from heaven is a profound and pivotal event in biblical theology, marking a decisive moment in the cosmic struggle between good and evil. Rooted in the narrative of the fall, this event is primarily described in the context of Satan's rebellion against God's authority. The origins of Satan, or Lucifer, trace back to his exalted position as a high-ranking angel in the heavenly realms. According to biblical accounts, Satan was not created as an inherently evil being but rather as a magnificent and powerful angel endowed with wisdom and beauty. However, the seeds of rebellion took root in his heart as he became consumed by pride and an insatiable desire to ascend to a position equal to or even surpassing that of God. The pivotal moment leading to Satan's expulsion can be found in Ezekiel 28 and Isaiah 14, where the prophet Ezekiel and Isaiah employ vivid imagery to describe the downfall of the once-glorious being. In Ezekiel 28:12-17, the King of Tyre is addressed in a passage that many scholars interpret as a dual reference to both an earthly king and the spiritual power behind him-Satan. The passage depicts Satan as having been in the garden of Eden, adorned with precious stones, and perfect in beauty until iniquity was found in him. His prideful heart led to his rebellion against God, resulting in his expulsion. Isaiah 14:12-15 provides additional insight into the prideful aspirations of Satan. The passage famously begins with the phrase "How you are fallen from heaven, O Lucifer, son of the morning!" It goes on to describe Satan's ambitious desire to exalt his throne above the stars of God and make himself like the Most High. This rebellious intent, rooted in pride and a thirst for power, became the catalyst for his ultimate expulsion.
