Revelation 4:1-3

Living Bible

4 Then as I looked, I saw a door standing open in heaven, and the same voice I had heard before, which sounded like a mighty trumpet blast, spoke to me and said, “Come up here and I will show you what must happen in the future!”

² And instantly I was in spirit there in heaven and saw—oh, the glory of it!—a throne and someone sitting on it! ³ Great bursts of light flashed forth from him as from a glittering diamond or from a shining ruby, and a rainbow glowing like an emerald encircled his throne.
