What are the seven bowl judgments in Revelation 15-16?
The context identifies them as the final seven judgments or plagues called the vials, or bowl judgments, in which God's wrath is finally consummated. They are pictured as bowls because a bowl can be poured out instantaneously, unlike other containers. The supplied context does not enumerate each of the seven individually.
Les explains that the wrath of God is finally consummated in these last seven judgments or plagues, which are called the vials in the King James or the bowl judgments. He notes that the reason for the bowl imagery is that you can pour out a bowl instantaneously, whereas a different container would take longer. In the vision that follows, John sees a sea of glass mingled with fire, and those who had gotten the victory over the beast standing there with the harps of God. These are the martyred tribulation saints already in the presence of the Lord in glory, having overcome the beast or antichrist, whom Satan is now indwelling, as well as his image, his mark, and the number of his name. Les adds that a verse like this gives people the idea that all we will do in heaven is strum a harp; that will certainly be part of it, but it will be more than just strumming harps. They then sing the song of Moses, the servant of God, and the song of the Lamb, which are two separate songs. The song of Moses is connected back to Exodus chapter 15, where Israel has just come through the Red Sea and is gathered around Mount Sinai, perhaps not even having quite arrived at Sinai yet.
And I saw another sign in heaven, great and marvellous, seven angels having the seven last plagues; for in them is filled up the wrath of God.
