Revelation 18:1-8
The fall of Babylon is described, and there are two areas: religious Babylon, and economic and political Babylon.
Revelation 17:6-18
Babylon the Great is pictured as an evil harlot, a phony church, and a city that rules over the wicked system. But the beast (Antichrist) will turn on the woman, and will burn her up. God sometimes turns the enemy's own swords against themselves.
Revelation 16:18-17:5
More of the Great Tribulation, when God judges what is referred to as "Mystery Babylon the Great, the mother of prostitutes and of the abominations on the earth." McGee says this represents a false church that departed from the Gospel.
Revelation 16:9-17
More about the "bowl judgments" of God during the Great Tribulation. It will be horrible and will be the last chance for sinful humanity to turn back to God; most, unfortunately, will not.
Revelation 15:8-16:8
The number seven is shown to be the number of completeness: Seven plagues during the Great Tribulation, seven bowls of God's wrath that are poured out on the earth.
Revelation 15:2-7
A dreadful look at the kinds of plagues which will happen to the sinners caught in the Great Tribulation. But God will keep his covenant with Israel and his people.
Revelation 14:20-15:1
A description of the reaping of the final harvest of earth, and it is a terrible picture of a scythe slicing through the armies who rebelled against God. Fearsome plagues befall the wicked!
Revelation 14:9-20
Warnings against receiving the Mark of the Beast, or Antichrist during the Great Tribulation, but also we get a preview of the terrible final judgment of God, the "harvest of the earth."
Revelation 14:5-8
During the Great Tribulation, an angel will fly overhead preaching the Gospel to the earth. But these days, God entrusts that business to His Church.
Revelation 14:1-4
Who are the 144,000 in the book of Revelation? These are standing with the Lamb of God, the Lord Jesus Christ singing a new song.
