Revelation 4:1-3

1Then 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.”

2And instantly I was in the Spirit, and I saw a throne in heaven and someone sitting on it.

3The 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.
