Charles H. Spurgeon on Psalms 135:7

He maketh lightnings for the rain. The Psalmist mentions it as another circumstance calling for our wonder, that lightnings are mixed with rain, things quite opposite in their nature one from another. Did not custom make us familiar with the spectacle, we would pronounce this mixture of fire and water to be a phenomenon altogether incredible. The same may be said of the phenomena of the winds. Natural causes can be assigned for them, and philosophers have pointed them out; but the winds, with their various currents, are a wonderful work of God. He does not merely assert the power of God, be it observed, in the sense in which philosophers themselves grant it, but he maintains that not a drop of rain falls from heaven without a divine commission or dispensation to that effect. All readily allow that God is the author of rain, thunder, and wind, in so far as he originally established this order of things in nature; but the Psalmist goes farther than this, holding that when it rains, this is not effected by a blind instinct of nature, but is the consequence of the decree of God, who is pleased at one time to darken the sky with clouds, and at another to brighten it again with sunshine. —John Calvin.
