Charles H. Spurgeon on Psalms 147:8

Clouds...rain...grass. There is a mutual dependence and subordination between all second causes. The creatures are serviceable to one another by mutual ministries and supplies; the earth is cherished by the heat of the heavens, moistened by the water, and by the temperament of both made fruitful; and so sendeth forth innumerable plants for the comfort and use of living creatures, and living creatures are for the supply of man. It is wonderful to consider the subordination of all causes, and the proportion they bear to one another. The heavens work upon the elements, the elements upon the earth, and the earth yieldeth fruits for the use of man. The prophet taketh notice of this admirable gradation: "I will hear the heavens, and the heavens shall hear the earth; and the earth shall hear the corn, and the wine, and the oil; and the corn, and the wine, and the oil, shall hear Jezreel" (Ho 2:21-22). We look to the fields for the supplies of corn, wine, and oil; but they can do nothing without clouds, and the clouds can do nothing without God. The creatures are beholden to one another, and all to God. In the order of the world there is an excellent chain of causes, by which all things hang together, that so they may lead up the soul to the Lord. —Thomas Manton.
