Charles H. Spurgeon on Psalms 14:1

"The fool hath said," etc. This folly is bound up in every heart. It is bound, but it is not tongue-tied; it speaks blasphemous things against God, it says there is "no God." There is a difference indeed in the language: gross sins speak this louder, there are crying sins; but though less sins speak it not so loud, they whisper it. But the Lord can hear the language of the heart, the whisperings of its motions, as plainly as we hear one another in our ordinary discourse. Oh, how heinous is the least sin, which is so injurious to the very being of the great God! David Clarkson.
