The Coming Demonic Invasion (Revelation 9:12–21)

This is a dynamite sermon. On a side note, in a lot of propaganda and psyops a signal is the number of 33. This has been theorized as related to the the Freemasons where you learn you serve Satan when you reach the 33rd and final level in their secret society, but watching this sermon I came upon a much simpler explanation as a third, or 33%, of angels rebelled against God. And in the Revelation as MarArthur points out, there are 13 references to a third, especially a third of mankind being killed when these currently bound 200 million demons are unleashed on the world. So could this simply be a reference to Satan and the other demons being behind it and pointing to their time as they prepare for the coming Tribulation?
