Luke 10:18

Jesus described the humiliation of Satan’s demons as though it was a repetition of Satan’s actual fall from heaven that happened before Creation. Isaiah’s description of the king of Babylon’s fall was similar (Isaiah 14:12). Many Bible students believe that Isaiah was describing the fall of Satan, but the context argues for a human king. Jesus may have been alluding to this passage. However, He appears to have been describing a current fall or humiliation symbolized by the subjection of the demons to His authority. This is more probable than that He described a vision that He had. Satan will experience similar humiliations in the future during the Tribulation (Revelation 12:7-10; Revelation 12:13), at the end of the Tribulation (Revelation 20:2), and at the end of the Millennium (Revelation 20:10). Jesus’ victory over Satan gave Him, as well as His disciples, cause for rejoicing.

"To the casual observer all that had happened was that a few mendicant preachers had spoken in a few small towns and healed a few sick folk. But in the gospel triumph Satan had suffered a notable defeat." [Note: Morris, p. 185.]
