Charles H. Spurgeon on Psalms 136:9

Stars. The stars not only adorn the roof of our sublunary mansion, they are also in many respects useful to man. Their influences are placid and gentle. Their rays, being dispersed through spaces so vast and immense, are entirely destitute of heat by the time they arrive at our abode; so that we enjoy the view of a numerous assemblage of luminous globes without any danger of their destroying the coolness of the night or the quiet of our repose. They serve to guide the traveller both by sea and land; they direct the navigator in tracing his course from one continent to another through the pathless ocean. They serve "for signs and for seasons, and for days and years." They direct the labours of the husbandman, and determine the return and conclusion of the seasons. They serve as a magnificent "time piece", to determine the true length of the day and of the year, and to mark with accuracy all their subordinate divisions. They assist us in our commerce, and in endeavouring to propagate religion among the nations, by showing us our path to every region of the earth. They have enabled us to measure the circumference of the globe, to ascertain the density of the materials of which it is composed, and to determine the exact position of all places upon its surface. They cheer the long nights of several months in the polar regions, which would otherwise be overspread with impenetrable darkness. Above all, they open a prospect into the regions of other worlds, and tend to amplify our views of the Almighty Being who brought them into existence by his power, and "whose kingdom ruleth over all." In these arrangements of the stars in reference to our globe, the Divine wisdom and goodness may be clearly perceived. We enjoy all the advantages to which we have alluded as much as if the stars had been created solely for the use of our world, while, at the same time, they serve to diversify the nocturnal sky of other planets, and to diffuse their light and influence over ten thousands of other worlds with which they are more immediately connected, so that, in this respect, as well as in every other, the Almighty produces the most sublime and diversified effects by means the most simple and economical, and renders every part of the universe subservient to another, and to the good of the whole. —Thomas Dick.
