At the opening of the sixth seal, there is
1. an earthquake
2. The sun becomes black
3. The moon becomes red
4. The stars fall like unripe figs
5. The heaven rolls back like a scroll
6. The mountains and islands are moved
The reference to the heavens rolling up like a scroll is a quote from Isaiah
Interestingly enough, the English word scroll is only used twice in the English Bible. But the word from which scroll is translated is used 184 times. In other places it is translated book (138x), letter (29x), evidence (8x), bill (4x), learning (2x), register (1x), learned (with H3045) (1x),scroll (1x).
A study of the things that are written in heaven is an extensive study that I will not get into now. Records that are kept in Biblical accounts were done for various reasons: to keep history or accounts, to keep laws and judgments, or for legal decrees. In the heavens, God keeps two types of books, the Book of Life, and the Book of the accounts of our works. I use the words scrolls and books interchangeably.
The seals being opened in revelation are for the scroll containing the judgments upon the world. There is no one worthy to open the scrolls except Jesus Christ who not only fulfilled all its laws but also suffered it’s judgment.
[Rev 5:1-5 KJV]
The books of the law are kept as “a witness against” whose who break it. It is evidence, as you would submit evidence in court. (The word for ‘scroll’ is actually translated ‘evidence’ in some scriptures)
[Deu 31:24, 26 KJV]
It is my opinion that the opening of the 6th seal reveals a literal opening (or closing perhaps) of the sky, which is itself a testament of God’s law and judgment. The sky itself will be submitted as evidence of God’s broken law and it will witness against mankind.
I also looked up the word for rolled up. Because this is a quote from Isaiah, we get a lot more contextual evidence from the word translated ‘rolled up’ because the word is used many times in the O.T. I was a bit confused wondering if the scroll was being rolled up to close it or being opened, because in Revelation, the sealed scroll is opened. But rolled is actually in all the other passages non specific. Some verses are rolling something closed like rolling a stone in front of a cave, and others are rolling it away to open it. But the word was used a lot in referring to judgments, which is interesting. A more complete understanding would be the way we use rolled like “roll out a new product” so there is actual rolling and figurative rolling in the Hebrew as there is in the English.
As to the sky being a testament, we use the phrase written in the sky, or written in the stars for good reason. David wrote an entire psalm to the sky being used as a written testament of God’s precepts. In fact, the psalm is prophetical psalm about Revelations. He refers to lightning (as the coming of Christ will be as lightning) and the whole earth witnessing it, and the salvation of Israel which is to be sealed right after the heaven is rolled back like a scroll.
[Psa 97:1-12 KJV]
The fact that the sun and moon and stars are to testify against man is ironic, since the idol worshippers used them to blaspheme God and worshipped them in His place.
