"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." At once I was in the Spirit, and there before me was a throne in heaven with someone sitting on it. And the one who sat there had the appearance of jasper and carnelian. A rainbow, resembling an emerald, encircled the throne. (Rev.4)
