Charles H. Spurgeon on Psalms 147:8

Who covereth the heaven with clouds. He works in all things, above as well as below. Clouds are not caused by accident, but produced by God himself, and made to assume degrees of density by which the blue firmament is hidden. A sky scape might seem to be a mere fortuitous concourse of vapours, but it is not so: the Great Artist's hand thus covers the canvas of the heavens. Who prepareth rain for the earth. The Lord prepares clouds with a view to rain, and rain with an eye to the fields below. By many concurrent circumstances all things are made ready for the production of a shower; there is more of art in the formation of a rain cloud and in the fashioning of a rain drop, than appears to superficial observers. God is in the vapour, and in the pearly drop which is born of it. Who maketh grass to grow upon the mountains. By the far reaching shower he produces vegetation where the hand of man is all unknown. He cares not only for Goshen's fertile plains, but for Carmel's steep ascents. God makes the heavens the servants of the earth, and the clouds the irrigators of the mountain meadows. This is a kind of evolution about which there can be no dispute. Nor does the Lord forget the waste and desolate places, but causes the lone hills to be the first partakers of his refreshing visitations. This is after the manner of our God. He not only causes rain to descend from the heavens to water the grass, and thus unites the skies and the herbs by a ministry of mercy; but he also thinks of the rocky ledges among the hills, and forgets not the pastures of the wilderness. What a God is this!

"Passing by the rich and great,

For the poor and desolate."
