Revelation 4:1-6

1 Then as I looked, I saw a door standing open in heaven, and the same voice I had heard before spoke to me like a trumpet blast. The voice said, “Come up here, and I will show you what must happen after this.”
2 And instantly I was in the Spirit, and I saw a throne in heaven and someone sitting on it.
3 The one sitting on the throne was as brilliant as gemstones—like jasper and carnelian. And the glow of an emerald circled his throne like a rainbow.
4 Twenty-four thrones surrounded him, and twenty-four elders sat on them. They were all clothed in white and had gold crowns on their heads.
5 From the throne came flashes of lightning and the rumble of thunder. And in front of the throne were seven torches with burning flames. This is the sevenfold Spirit of God.
6 In front of the throne was a shiny sea of glass, sparkling like crystal. In the center and around the throne were four living beings, each covered with eyes, front and back.
