The Throne in Heaven

1 After this I looked, and there before me was a door standing open in heaven. And the voice I had first heard speaking to me like a trumpet said, “Come up here, and I will show you what must take place after this.”
2 At once I was in the Spirit, and there before me was a throne in heaven with someone sitting on it.

3 And the one who sat there had the appearance of jasper and ruby. A rainbow that shone like an emerald encircled the throne.
4 Surrounding the throne were twenty-four other thrones, and seated on them were twenty-four elders. They were dressed in white and had crowns of gold on their heads.
