After this I looked, and there in front of me was a door standing open in heaven. I heard the voice I had heard before. It sounded like a trumpet. The voice said, "Come up here. I will show you what must happen after this."
References for Revelation 4:1
At once the Holy Spirit took complete control of me. There in front of me was a throne in heaven with someone sitting on it.
The One who sat there shone like jewels. Around the throne was a rainbow that looked like an emerald.
Twenty-four other thrones surrounded that throne. Twenty-four elders were sitting on them. The elders were dressed in white. They had gold crowns on their heads.
From the throne came flashes of lightning, rumblings and thunder. Seven lamps were blazing in front of the throne. These stand for the seven spirits of God.
There was something that looked like a sea of glass in front of the throne. It was as clear as crystal. In the inner circle, around the throne, were four living creatures. They were covered with eyes, in front and in back.
The first creature looked like a lion. The second looked like an ox. The third had a man's face. The fourth looked like a flying eagle.
Each of the four living creatures had six wings. Each creature was covered all over with eyes, even under the wings. Day and night, they never stop saying, "HOLY, HOLY, HOLY IS THE LORD GOD WHO RULES OVER ALL. HE WAS, AND HE IS, AND HE WILL COME."
The living creatures give glory, honor and thanks to the One who sits on the throne and who lives for ever and ever.
At the same time, the 24 elders fall down and worship the One who sits on the throne and who lives for ever and ever. They lay their crowns in front of the throne. They say,
"You are worthy, our Lord and God! You are worthy to receive glory and honor and power. You are worthy because you created all things. They were created and they exist. That is the way you planned it."
