V.1 A star, someone in great political power, falls from the heavens.
V.1-3 Dreadful calamities come on the earth as a result of his coming. The bottomless pit is opened. What a terrible day that will be for this poor world of the unsaved. And just to realize too that all this will take place shortly after the Lord Jesus has taken the believers to heaven. We believers will not pass through the tribulation (Rev. 3:1010Because thou hast kept the word of my patience, I also will keep thee from the hour of temptation, which shall come upon all the world, to try them that dwell upon the earth. (Revelation 3:10)). Satan’s power is seen increasing in these 3 verses. The Holy Spirit which is on earth today, holds back Satan’s power. But at that time, the Holy Spirit has gone back to heaven, and Satan will have great power.
V.4-6 Many Jews will not believe the gospel of the coming kingdom, and these verses describe those unbelieving Jews.
V.7-21 Forms of wickedness which before this have been held back, will now break out. These verses seem to be referring to the East — Euphrates river (v. 14).
