Charles H. Spurgeon on Psalms 84:11

The Lord God is a sun, conveys a striking and impressive truth, when we think of the sun only in his obvious character as a source of light and heat. But what new energy is given to this magnificent emblem, when we learn from astronomy that he is a grand center of attraction, and when we, in addition, take in that sublime generalization that the sun is the ultimate source of every form of power existing in the world! The wind wafts the commerce of every nation over the mighty deep; but the heat of the sun has rarefied that air, and set that wind in motion. The descending stream yields a power which grinds your grain, turns your spindles, works your looms, drives your forges; but it is because the sun gathered up the vapour from the ocean, which fell upon the hills, and is finding its way back to the source whence it came. The expansive energy of steam propels your engine; but the force with which it operates is locked up in the coal (the remains of extinct forests stored among your hills), or is derived from the wood that abounds in your forests, which now crown and beautify their summits. Both these primeval and these existing forests drew their substance from the sun: it is the chemical force resident in his rays which disengaged their carbon from the atmosphere, and laid it up as a source of power for future use. The animal exerts a force by muscular contraction; he draws it from the vegetable on which he feeds; the vegetable derives it from the sun, whose rays determine its growth. Every time you lift your arm, every time you take a step, you are drawing on the power the sun has given you. When you step into the railway carriage, it is the sun power that hurries you along. When gentle breezes fan your languid cheek, and when the restless tornado levels cities in its fury, they are the servants of the sun. What an emblem of Him in whom we live, and move, and have our being! Professor Green.
