Charles H. Spurgeon on Psalms 135:7

He maketh lightnings for the rain. When the electrical clouds are much agitated, the rain generally falls heavily, and if the agitation is excessive, it hails. As the electricity is dissipated by the frequent discharges the cloud condenses, and there comes a sudden and heavy rain; but the greater the accumulation of electricity, the longer is the rain delayed. Thus connected as the electrical phenomena of the atmosphere are with clouds, vapour, and rain, how forcibly are we struck with these appropriate words in the Scriptures. —Edwin Sidney, in "Conversations on the Bible and Science," 1866.
