This rainbow is comprised of the 63,779 cross-references in the Bible. The white bars along the bottom represent each Bible chapter, Genesis to Revelation. A cross-reference is a verse that echoes or confirms another verse. This would be amazing even if the Bible had been written by one person or at one time but the Bible was written by 40 authors over the span of 1500 years on 3 different continents.
The Bible is complex, diverse, and intricate, and yet it has one unified message: “For here is the way God loved the world—he gave his only, unique Son as a gift. So now everyone who believes in him will never perish but experience everlasting life.”
‭‭John‬ ‭3:16‬ ‭TPT‬‬

Interesting image, I see a flat plane covered by a dome.
