at the voice of God the earth itself melts. [Psalm 46:6 CEV]
Sacred Texts . com has this to say about the passage:
He uttered his voice – God spoke; he gave command; he expressed his will.
The earth melted – The very earth seemed to melt or dissolve before him. Everything became still. The danger passed away at his command, and the raging world became calm.
The goal of meltingearth is to facilitate this impact, this effect, through better art.
