From the throne came flashes of lightning, and rumblings and peals of thunder, and before the throne were burning seven torches of fire, which are the seven spirits of God, and before the throne there was as it were a sea of glass, like crystal ... Then I heard what seemed to be the voice of a great multitude, like the roar of many waters and like the sound of mighty peals of thunder, crying out, "Hallelujah!For the Lord our God the Almighty reigns. Let us rejoice and exult and give him the glory, for the marriage of the Lamb has come, and his Bride has made herself ready; it was granted her to clothe herself with fine linen, bright and pure"— for the fine linen is the righteous deeds of the saints. And the angel said to me, "Write this: Blessed are those who are invited to the marriage supper of the Lamb."
(Rev 4:5-6; 19:6-9 ESV)
