The text does not actually state that Satan was in heaven, nor that he literally fell from heaven. Rather, Jesus uses a simile
“as.” The comparison is not that Satan fell from heaven in the same way lightning does, but that Satan’s defeat was as sudden and as striking as lightning flashing from the sky.
The context makes this clear: Jesus is speaking about the casting out of demons, not the fall of a rebellious angel (v. 17).
The word
Satan (Greek: “adversary”) is used by Jesus to describe the binding power of sin, often seen in disease. Several passages illustrate this:
- Luke 11:14–23 — A mute man, described as demon-possessed (v. 14), is said to be bound within the “house” of Satan (vv. 17–18). His healing is then described as the arrival of the kingdom of God, because the King’s power had broken through (vv. 20–22).
- Luke 13:10–17 — A woman crippled for eighteen years is said to have “a spirit of infirmity” (v. 11). Yet Jesus also describes her as “a daughter of Abraham, whom Satan has bound these eighteen years” (v. 16).
In this way, the victory of the seventy over demons was really the dethronement of Satan — the adversary — in his “house.” Their cures were so complete and immediate that Jesus likened the fall of Satan to the sudden flash of lightning.
Still, Jesus redirects their joy. Rather than rejoicing in their power over demons, they were to rejoice that their names were written in heaven (Luke 10:20).
