Charles H. Spurgeon on Psalms 74:17

Thou hast set all the borders of the earth. Consider the form of the earth. It is known to be globular, and in shape nearly like an orange. And why has God chosen that form? With a view that it might be inhabited by living creatures on its whole surface. In order to this, every part of the globe must have sufficient light and heat, the wind must have a free circulation, and the water must be diffused over all its parts. The rotundity of the earth is best calculated to promote these conveniences: for this round form admits light and heat, without which there could be no life all over the globe. The revolutions of day and night, the changes in the temperature of the air, heat, cold, dryness or moisture, could not have taken place without this form. Had the earth been square, had it been conic, had it been an hexagon, or any other angular form, what must the consequence have been? The greatest part of our earth would have been drowned, whilst the rest, would have languished with drought. Some countries must have been torn in pieces by storms, while others would have been deprived of the wholesome circulation of wind. I have new reason to admire the supreme wisdom, when I reflect on the enormous mass which composes our world. Were the earth softer, or more spongy than it is, men and animals would sink into it; were it harder and less penetrable, it would resist the toil of the labourer, and lose its capacity for producing and nourishing the multitude of plants, herbs, roots, and flowers, which now spring out of its bosom. There are regular and distinct strata found in the earth; some of stone, others of metal and minerals. There are numerous and evident advantages which result from these in favour of mankind. Do not the strata of gravel, sunk deep in the earth, purify and in a manner filter the water and render it sweet and fit for use? On the surface of the earth there is a varied prospect; there is an admirable mixture of plains and valleys, of small hills and mountains. The man must be blind indeed that does not see the wise purpose of the Great Author of nature, in thus diversifying the surface of the earth. Were the earth an even plain, how much beauty would it lose? Besides, this variety of valley and mountain is very favourable to the health of living creatures, and were there no hills, the earth would be less peopled with men and animals. There would be fewer plants, fewer simples and trees. We should be deprived of metals and minerals: the vapours would not be condensed, nor should we have either springs or rivers. Must we not then acknowledge that the whole plan of the earth, its form, its inward and outward construction, are all regulated according to the wise laws, which all combine towards the pleasure and happiness of mankind? O thou supreme Author of nature, thou hast done all things well! Whichever way I turn my eyes, whether I penetrate into the interior structure of the globe thou hast appointed me to inhabit, or whether I examine its surface, I everywhere discover marks of profound wisdom and infinite goodness.
