The text for the day’s lesson was Rev 16:1-7, but the portion discussed here, during our review of the previous week’s lesson, was Rev 15:1-4
Revelation 15:1-4 (HCSB)
1 Then I saw another great and awe-inspiring sign in heaven: seven angels with the seven last plagues, for with them, God’s wrath will be completed.
2 I also saw something like a sea of glass mixed with fire, and those who had won the victory over the beast, his image, and the number of his name, were standing on the sea of glass with harps from God.
3 They sang the song of God’s servant Moses and the song of the Lamb: Great and awe-inspiring are Your works, Lord God, the Almighty; righteous and true are Your ways, King of the Nations.
4 Lord, who will not fear and glorify Your name? Because You alone are holy, for all the nations will come and worship before You because Your righteous acts have been revealed.
