QC,
I liked what you did putting those two verses together. Luke 10:17 and Revelation 12:7. In Luke Jesus talk about a "fall", "serpents" and "scorpions", in Revelation, it talks aout "serpents", a "fall" and other angels, could they be "scorpions"? "serpents" related?
I think 1914 as the date of Satan fall to earth is out of the question. You arrive at 1914 through Daniel's big tree, which only applies to Nabo, not Jehovah's Kingdom. Plus, in Matthew 28:19,20 Jesus said that he received all power on earth and heaven right after resurrection.
