The Bible , John Vision :
After Jesus finished addressing the seven churches, I looked and saw a door standing open in heaven! And the first voice which I had heard again addressed me like the calling of a trumpet and said to me, "Come up here, and I will show you what must take place in the future. " And immediately I came under the Holy Spirit’s power and I saw a throne standing in heaven, with someone seated on it! And He Who sat upon the throne radiated light like diamonds and rubies and all around His throne was a halo that looked like an emerald rainbow.
Twenty-four other thrones surrounded the main throne, and seated on these thrones were twenty-four elders all dressed in white spotless clothing, with crowns of gold upon their heads. Out from the central throne came flashes of lightning and rumblings of thunder, and in front of this throne seven blazing torches burned, which represented the sevenfold perfect Spirit of God. And in front of the throne there was also what looked like a transparent glassy sea like a crystal, still and calm and safe. And around the throne, in the center at each side of the throne, were all the saved, seeing what is before and behind them, noble, penitent, wise and soaring on the wings of eagles, high above the earth.
And when they all offer glory, honor and thanksgiving to God who sits on His throne and will never die, all the elders throw their crowns at God’s feet and fall on their faces with them and join them in worship, crying out “Worthy are You, our Lord and God, to receive the glory and the honor and dominion, for You created all things and by Your will they were brought into being and were created.”
