God hangs the earth on nothing (Job 26:7).
That’s literally true. There’s no changeless substance beneath the surface of change, nothing holding us up, making it all stable and safe.
There’s nothing holding creation in place except God.
Every effort to hang the world on something, every effort to find some stable foundation in the creation, is idolatry.
It’s one of the most persistent and pious forms of idolatry.
