Then I saw another sign in heaven, great and marvelous, seven angels who had seven plagues, which are the last, because in them the wrath of God is finished. Revelation 15:1

We begin a new scene of Gods Final Judgment and the victory over Satan! Notice the number 7 again, which symbolizes completion. 7 Angels/Messengers  + 7 plagues = wrath of God is finished

And I saw something like a sea of glass mixed with fire, and those who had been victorious over the beast and his image and the number of his name, standing on the sea of glass, holding harps of God. Revelation 15:2

The “Sea of Glass” John mentions here is a mystery, in his imagery we can guess that because it’s a sea, it’s a very large area, therefor I would assume there are a large group of Christians standing here. The Fire I would guess is symbolic of the Holy Spirit that is empowering all of us Christians. Praising God by playing music and worshipping to the Lord in Victory!

And they sang the song of Moses, the bond-servant of God, and the song of the Lamb, saying, “Great and marvelous are Your works, O Lord God, the Almighty; Righteous and true are Your ways, King of the nations! Who will not fear, O Lord, and glorify Your name? For You alone are holy; For ALL THE NATIONS WILL COME AND WORSHIP BEFORE YOU, FOR YOUR RIGHTEOUS ACTS HAVE BEEN REVEALED.” Revelation 15:3-4

The “Song of Moses” is the same song sang when the Israelites were freed in the Exodus and God parted the Red Sea for them. The parallels between the Exodus and Revelation are amazing. God sent the plaques to Egypt while God sent the Tribulation here. Moses freed the Israelites from slavery while Jesus has freed us from the slavery of sin and death. Egypt has the evil leader Pharaoh, while Revelation Satan has the Anti Christ

Regardless this is a time of celebration right now, as final Judgement is coming upon Satan and eternal victory through Christ and his followers!

Then Moses and the sons of Israel sang this song to the LORD, and said, “I will sing to the LORD, for He is highly exalted; The horse and its rider He has hurled into the sea. Exodus 15:1

After these things I looked, and the temple of the tabernacle of testimony in heaven was opened, and the seven angels who had the seven plagues came out of the temple, clothed in linen, clean and bright, and girded around their chests with golden sashes. Revelation 15:5-6

The Temple of the Tabernacle of Testimony, we can assume this is the Ark of the Covenant (The Ten Commandments) meaning Justice has been served! No longer will evil remain on this Earth, its being purged along with Satan and his followers

Notice the 7 Angels have golden sashes around their chests. This is symbolic for authority given to them. They have been granted authority by God to carry out final judgement of the Earth and Satan

who serve a copy and shadow of the heavenly things, just as Moses was warned by God when he was about to erect the tabernacle; for, “SEE,” He says, “THAT YOU MAKE all things ACCORDING TO THE PATTERN WHICH WAS SHOWN YOU ON THE MOUNTAIN.” Hebrews 8:5

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. And the temple was filled with smoke from the glory of God and from His power; and no one was able to enter the temple until the seven plagues of the seven angels were finished. Revelation 15:7-8

The Bowls of Gods wrath are about to be unleashed on the Earth. Notice the Temple was filled with smoke, the smoke symbolizing Gods presence. Nobody was able to enter the Temple until it was finished! This is the final judgement , no second chances, time is up!

Therefore when Jesus had received the sour wine, He said, “It is finished!” And He bowed His head and gave up His spirit. John 19:30
