+III. That the world which God has made bears the impress of Infinite Wisdom.+ Scientific investigation and discovery bear out the assertion of Solomon, that the Lord "by wisdom founded the earth." The discoveries of astronomers reveal to us more and more the "understanding" which "established the heavens." Solomon here selects one example of the wisdom of God, as displayed in relation to the earth, viz., the process by which it is watered--by which God "maketh it soft with showers, and thus blesseth the springing thereof" (Psa. lxv. 10), and so gives seed to the sower and bread to the eater. This "philosophy of rain," as it has been called, is one which illustrates creative wisdom in a remarkable manner. Dr. Ure says, "To understand the philosophy of the beautiful and often sublime phenomenon, so often witnessed since the creation of the world, and essential to the very existence of plants and animals, a few facts derived from observation and a long train of experiments must be remembered. (1) Were the atmosphere everywhere at all times of a uniform temperature we should never have rain, or hail, or snow; the water absorbed by it in evaporation from the sea and the earth's surface would descend in an imperceptible vapour, or cease to be absorbed by the air when it was once fully saturated. (2) The absorbing power of the atmosphere, and consequently its capability to retain humidity, is proportionately greater in warmer than in cold air. (3) The air near the surface of the earth is warmer than it is in the region of the clouds. The higher we ascend from the earth, the colder do we find the atmosphere. Hence the perpetual snow on very high mountains in the hottest climate. Now, when from continued evaporation the air is highly saturated with vapour, though it be invisible and the sky cloudless,--if its temperature be suddenly reduced by cold currents descending from above, or rushing from a higher to a lower latitude, its capacity to retain moisture is diminished, clouds are formed, and the result is rain. Air condenses as it cools, and, like a sponge filled with water and compressed, pours out the water which it cannot hold. How singular, yet how simple, the philosophy of rain. Who but Omniscience could have devised such an admirable arrangement for watering the earth?" Solomon could not have known _how_ the earth was watered, but he knew enough to awaken his admiration of Providential love and skill. +IV. The exhibition of God's wisdom in creation is intended to lead men to listen to his Word of Revelation.+ To this end the subject is introduced here by the preacher. When such a Being speaks, it must be worth men's while to listen and obey. The heavens and earth have a speech or language (Psa. xix. 1, 2). They counsel us to seek Him "who hath measured the waters in the hollow of His hand, and meted out heaven with the span, and comprehended the dust of the earth in a measure,"--Him "whose word shall stand for ever" (Isa. xl.).
