Charles H. Spurgeon on Psalms 14:4

Hatred of God and corruptness of life are the motive forces which produce persecution. Men who having no saving knowledge of divine things, enslave themselves to become workers of iniquity, have no heart to cry to the Lord for deliverance, but seek to amuse themselves with devouring the poor and despised people of God. It is hard bondage to be a "worker of iniquity;" a worker at the galleys, or in the mines of Siberia, is not more truly degraded and wretched; the toil is hard and the reward dreadful: those who have no knowledge choose such slavery, but those who are taught of God cry to be rescued from it. The same ignorance which keeps men bondsmen to evil, makes them hate the freeborn sons of God; hence they seek to eat them up "as they eat bread," —daily, ravenously, as though it were an ordinary, usual, every-day matter to oppress the saints of God. As pikes in a pond, eat up little fish, as eagles prey on smaller birds, as wolves rend the sheep of the pasture, so sinners naturally and as a matter of course, persecute, malign, and mock the followers of the Lord Jesus. While thus preying, they forswear all praying, and in this act consistently, for how could they hope to be heard while their hands are full of blood?
