Charles H. Spurgeon on Psalms 104:12

By them shall the fowls of the heaven have their habitation, etc. To such birds may saints be compared; being, like them, weak, defenceless, and timorous; liable to be taken in snares, and sometimes wonderfully delivered; as well as given to wanderings and straying; and to fowls of the heaven, being heaven born souls, and partakers of the heavenly calling. These have their habitation by the fountain of Jacob, by the river of divine love, beside the still waters of the sanctuary, where they sing the songs of Zion, the songs of electing, redeeming, and calling grace. John Gill.
