They Have No Light

Jeremiah 4:23-26 ESV
I looked on the earth, and behold, it was without form and void;
and to the heavens, and they had no light.
24 I looked on the mountains, and behold, they were quaking,
and all the hills moved to and fro.
25 I looked, and behold, there was no man,
and all the birds of the air had fled.
26 I looked, and behold, the fruitful land was a desert,
and all its cities were laid in ruins
before the Lord, before his fierce anger.

The Lord speaks of a creation that has regressed back to its formless dark state as a result of the rejection and willfulness by Israel and Judah.
They leave behind their Creator and God. They have no light.
