Charles H. Spurgeon on Psalms 97:2

Darkness. This and the four following verses have a striking resemblance to the awful pomp of the march of God, as described Ps 18:8-9 Ps 68:8. All the dread phenomena and meteoric array of nature are in attendance; thunder and lightning, and earthquakes and volcanoes, with streams of melting lava, like streams of melting wax. Yet all is justice and equity, joy, exultation, and glory; and the wicked alone —the adversaries of Jehovah —feel his judgments —the host of idols and their brutish worshippers. —John Mason Good.
