Charles H. Spurgeon on Psalms 49:20

Like the beasts that perish. Sin is both formaliter and effective vile. As it is so in itself, so it has made man vile. No creature so debased as man, being in this respect become viler than any creature. There is no such depravation in the nature of any creature, except in the diabolical nature. No creature ever razed God's image out of its nature, but only man. There is no aversions to the will of God, no inclination to what offends him, in any creature on earth but man. Man, then, who was once the glory of the creation, is become the vilest of all creatures, for that is vilest which is most contrary to the infinite glory, but so is our nature, "Man being in honour, abideth not, "is now like the beast that perish; nay, worse than they, if the greatest evil can make him worse. Man was made a little lower than the angels, crowned with glory, advanced to be lord and governor of all the works of his hands; and all creatures in this world were put under his feet. Ps 8:5-6. But by this natural corruption he that was but a little lower than the angels is now something below the beasts. He was to have dominion, but is made baser than those over whom he rules. They were put under his feet, but now he is as low as they. This is the sad issue of natural corruption. David Clarkson.
