What does Revelation 15:3 mean?
The harpists joined in singing two songs: the song of Moses and the song of the Lamb. Both songs celebrate redemption by God's almighty hand. The song of Moses was sung initially on the banks of the Red Sea after God had miraculously led His people through the Red Sea and then drowned Egypt's cavalry in the rushing water (Exodus 15).Similarly, God had triumphed over the beast on behalf of His tribulation saints. The song of the Lamb presumably celebrates Jesus as the Passover Lamb, whose blood redeemed the tribulation saints. They extoll the Lord as performing great and amazing deeds that only the Almighty one could perform. They characterize the Lord as just and true in His ways. His judgments are just, and He makes no mistakes because His ways are true. The wicked deserve the punishment they are about to receive. Further, the saints characterize the Lord as the "King of the nations." Following His judgments, no wicked person will be left to enter Jesus' earthly kingdom. The King of kings and Lord of lords will take custody of the nations.
