He sendeth the springs into the valleys - Evaporation is guided and regulated by Divine Providence. The sun has a certain power to raise a certain portion of vapours from a given space. God has apportioned the aqueous to the terrene surface, and the solar attraction to both. There is just as much aqueous surface as affords a sufficiency of vapours to be raised by the solar attraction to water the earthy surface. Experiments have been instituted which prove that it requires a given space of aqueous surface to provide vapours for a given space of terrene surface; and the proportion appears ordinarily to be seventeen of water to three of earth; and this is the proportion that the aqueous bears to the terrene surface of the globe. See Ray's three Physico-theological Discourses.

Psalm 107:35 He turns the wilderness into a standing water, and dry ground into springs.

The waters of the sea are not only prevented from destroying the earth, but, by the providence of God, are rendered the means of preserving every living thing; partly ascending from the great deep through the strata of the earth, partly exhaled in vapour from the surface of the ocean, and thence falling in rain, especially on the tops and sides of mountains, they break forth into fresh springs, and form streams and rivers.

Lessons from Nature
This prejudice against the beauties of the material universe reminds me of the lingering love to Judaism, which acted like a spell upon Peter of old. When the sheet knit at the four corners descended before him, and the voice said, "Rise, Peter; kill, and eat," he replied that he had not eaten anything that was common or unclean. He needed that the voice should speak to him from heaven again and again before he would fully learn the lesson, "What God hath cleansed that call not thou common." The …

The Creaturely Man.
"The Spirit of God hath made me, and the breath of the Almighty hath given me life."-- Job xxxiii. 4. The Eternal and Ever-blessed God comes into vital touch with the creature by an act proceeding not from the Father nor from the Son, but from the Holy Spirit. Translated by sovereign grace from death unto life, God's children are conscious of this divine fellowship; they know that it consists not in inward agreement of disposition or inclination, but in the mysterious touch of God upon their spiritual …

Of Confirmation.
It is surprising that it should have entered any one's mind to make a Sacrament of Confirmation out of that laying on of hands which Christ applied to little children, and by which the apostles bestowed the Holy Spirit, ordained presbyters, and healed the sick; as the Apostle writes to Timothy: "Lay hands suddenly on no man." (1 Tim. v. 22.) Why not also make a confirmation out of the sacrament of bread, because it is written: "And when he had received meat, he was strengthened" (Acts ix. 19); or …
