and a part that was absolutely HILARIOUS in the Bible was...I believe a few of Jesus disciples were acting kinda shook of Satan, and the war in Heaven came up, and Jesus had patience at first, but they just kept asking questions about the war, this isn't verbatim, but Jesus basically gets tired of the questions and say 'I saw Satan fall from Heaven like lightning'
Jesus's response to that disciple was in response to to the disciple saying even demons submit to them. This is basically saying that Satan had been defeated in Heaven and was now wreaking havoc on earth because his end was near. Recall, in nearly every encounter in which Jesus cast out a demon, the demon feared that final judegement was imminent and begged for mercy. Read Luke 10:17-19.
