Charles H. Spurgeon on Psalms 136:25

Who giveth food to all flesh. Common providence, which cares for all living things, deserves our most devout thanks. If we think of heavenly food, by which all saints are supplied, our praises rise to a still greater height; but meanwhile the universal goodness of God in feeding all his creatures is as worthy of praise as his special favours to the elect nation. Because the Lord feeds all life therefore we expect him to take special care of his own family. For his mercy endureth for ever. Reaching downward even to beasts and reptiles, it is, indeed, a boundless mercy, which knows no limit because of the meanness of its object.

"All things living he doth feed,

His full hand supplies their need;

For his mercy shall endure,

Ever faithful, ever sure."
