Revelation 21:23 is a reference to the book of Revelation, Chapter 21, Verse 23 which reads:
And the city has no need of sun or moon, for the glory of God illuminates the city, and the Lamb is its light.
The sun has given answers to both science and religion, working as a unifying symbol.
The video on the left focus on meteorology’s connection to the sun and prediction of the weather, but with identities cropped, leaving the hands working as a type of prophet
The video on the right is a close up of Christ after the resurrection in stained glass with the sun illuminating its image.
The audio is layered, the first stream being a choir singing “Miserere mei, Deus” slowed down at the translated line “Have mercy on me, O God”
The other stream of audio is a solar panel which has been adapted to convert light into sound, recording the sun’s light and creating as a result a white noise.
