Revelation 15:2-4

I saw before me what seemed to be a glass sea mixed with fire. And on it stood all the people who had been victorious over the beast and his statue and the number representing his name. They were all holding harps that God had given them. And they were singing the song of Moses, the servant of God, and the song of the Lamb: “Great and marvelous are your works, O Lord God, the Almighty. Just and true are your ways, O King of the nations. Who will not fear you, Lord, and glorify your name? For you alone are holy. All nations will come and worship before you, for your righteous deeds have been revealed.”
