Views vary among believers as the Bible does not give us an exact date that satan and his angels were cast out. However an examination of Revelation chapter 12 in light of what Jesus said confirms the approximate time. It also provides a lovely example of how prophetic revelation works in helping us have clarity on the future but also understand the past and present. The writer of Revelation Apostle John is given a fascinating glimpse into what took place in the invisible spirit realm. This is an example of word of knowledge, where prophetic revelation shows us what happens in the unseen realm.
