Charles H. Spurgeon on Psalms 74:20

The psalmist moves God in prayer to look to his covenant by this argument: For the dark places of the earth are full of the habitations of cruelty; that is, of cruel men, or of men so full of cruelty, that they deserve rather to be called cruelty than cruel: this sort of men inhabit and fill up all those places where the light of holy truth doth not shine. Now, if they who want the light, or have no true knowledge of God among them, are hereby prepared for the acting of all manner of wickedness, how much more are they prepared for the acting of wickedness who have thrust the light from them, and are in dark places of their own making? The prophet Hosea shows (Ho 4:1), that where there is no knowledge of God in a land, for want of means, there is no truth nor mercy (that is, there is none exercised) in that land, but oppression, deceit, and falsehood bear down all: how much more must it be so when there is no knowledge of God in a land, because of the contempt of means, and rebellion against the light? What wickedness will not they do in the dark, who put out the candle that they may not see what they do? Joseph Caryl.
