Revelation 15, three visions in heaven.
In Rev. 15 is John’s description of 3 visions (signs) in heaven before the final series of the 7 bowl judgments starts in Rev. 16. It is the calm before the storm.
V 1, Then I saw another sign in heaven, great and marvelous: seven angels having the seven last plagues, for in them the wrath of God is complete.
John’s first vision in heaven: 7 angels carrying 7 bowls filled up with the wrath of God.
God waited 400 years for the Amorites to repent but they did not. When the 400 years is up and the bowl of iniquity was full, God executed judgment. Genesis 15: 13-16, “Then the Lord said to him, “Know for certain that for four hundred years your descendants will be strangers in a country not their own and that they will be enslaved and mistreated there. But I will punish the nation they serve as slaves, and afterward they will come out with great possessions. You, however, will go to your ancestors in peace and be buried at a good old age. In the fourth generation, your descendants will come back here, for the sin of the Amorites has not yet reached its full measure’’.
Rev. 6:10, And they (the tribulation martyrs) cried with a loud voice, saying, “How long, O Lord, holy and true, until You judge and avenge our blood on those who dwell on the earth?”
V 2, And I saw something like a sea of glass mingled with fire, and those who have the victory over the beast, over his image and over his mark and over the number of his name, standing on the sea of glass, having harps of God.
John’s second vision in heaven: tribulation martyrs standing on a sea of glass worshipping God with the harps. They did not worship the image or receive the mark of the beast.
VV 3-4, 3 They sing the song of Moses, the servant of God, and the song of the Lamb, saying: “Great and marvelous are Your works, Lord God Almighty! Just and true are Your ways, O King of the saints! 4 Who shall not fear You, O Lord, and glorify Your name? For You alone are holy. For all nations shall come and worship before You, For Your judgments have been manifested.”
They sang the song of Moses on the sea of glass. The Israelites sang this song after crossing the Red Sea. Exodus 15:1, “Then sang Moses and the children of Israel this song unto the Lord, and spake, saying, I will sing unto the Lord, for he hath triumphed gloriously: the horse and his rider hath he thrown into the sea”.
They sang the song of the Lamb, acknowledging the greatness of God’s miracles, Name, holiness, glory, and righteousness in executing judgments on the nations.
VV 5-6, 5 After these things I looked, and behold, the temple of the tabernacle of the testimony in heaven was opened. 6 And out of the temple came the seven angels having the seven plagues, clothed in pure bright linen, and having their chests girded with golden bands.
John’s third vision: heaven opened and the 7 angels holding the 7 plagues comes out from the temple. These 7 angels wore pure bright linens and girded their chests with golden bands.
VV 7-8, 7 Then one of the four living creatures gave to the seven angels seven golden bowls full of the wrath of God who lives forever and ever. 8 The temple was filled with smoke from the glory of God and from His power, and no one was able to enter the temple till the seven plagues of the seven angels were completed.
One of the 4 living creatures gave the 7 golden bowls filled with God’s wrath to the 7 angels with the 7 plagues. The glory of God filled the temple and no one could enter until the 7 plagues of the 7 angels were completed i.e. until sin had been judged and cleansed.
God’s glory manifested when King Solomon dedicated the temple. 2 Chronicles 7: 1-2, ‘’When Solomon had finished praying, fire came down from heaven and consumed the burnt offering and the sacrifices; and the glory of the Lord filled the temple. And the priests could not enter the house of the Lord, because the glory of the Lord had filled the Lord’s house’’.
