Q: Hi Dr. E, Based on Revelation 12:9, when was Satan cast out of heaven? Could you give me Scriptures for your reasoning? Thanks so much! Summary In this episode, Dr. E unpacks Revelation 12:9 and explores what Scripture reveals about Satan’s fall, his defeat, and final judgment. From his rebellion and role in Eden to his defeat at the cross and expulsion during the tribulation, Dr. E outlines the key stages of Satan’s downfall. He addresses the complex theological implications of evil still being active even as believers are with God in heaven. Dr. E also explains the shifting scholarly interpretations of Isaiah and Ezekiel, passages long associated with Satan but increasingly seen as addressing earthly kings. He affirms that while some details remain mysterious, the overarching truth is clear: Satan is a defeated enemy, and God is sovereign over all. The question of whether there is mourning in heaven today is ultimately tied to the hope of final restoration. While sorrow may exist in a limited or temporary sense, heaven is defined by God’s presence—and His plan leads to a future where mourning is forever removed. Takeaways Satan's defeat was pronounced in Eden and finalized at the cross. Revelation 12 places Satan’s final expulsion during the tribulation. Solid theological resources help us navigate complex doctrines. God's sovereignty and ultimate victory are never in doubt. Theology should lead to faithful living, not just curiosity.
