The throne room of God is described in Revelation Chapter 4:1-5 in detail.
After these things I looked, and behold, a door standing open in heaven. And the first voice which I heard was like a trumpet speaking with me, saying, “Come up here, and I will show you things which must take place after this.” 2 Immediately I was in the Spirit; and behold, a throne set in heaven, and One sat on the throne. 3 And He who sat there was like a jasper and a sardius stone in appearance; and there was a rainbow around the throne, in appearance like an emerald. 4 Around the throne were twenty-four thrones, and on the thrones I saw twenty-four elders sitting, clothed in white robes; and they had crowns of gold on their heads. 5 And from the throne proceeded lightnings, thunderings, and voices. Seven lamps of fire were burning before the throne, which are the seven Spirits of God. Revelation 4:1-5
I did a research of what this throne room looks like and managed to find this from the internet.
Given that the picture above has attempted to factor in the verses that say God dwells in a light that cannot be approached.
1st Timothy 6:16
who alone is immortal and who lives in unapproachable light, whom no one has seen or can see. To him be honor and might forever. Amen.
Paul who was also inspired by Jesus wrote a letter to Timothy and describes God as dwelling in a light that cannot be approached and mentions two important facts about God.
No one has ever seen God, not even Jesus or the Spirit. This is similar to the knowledge about The Return of the Son of Man when Jesus disqualifies himself and the angels from knowing about his second coming.
No one can see God. This means not even John saw God in the vision in Revelation.
So what is the Jasper and sardius stone color description John used to describe God with?
