Charles H. Spurgeon on Psalms 36:2

For he flattereth himself in his own eyes. The matter which this self flattery especially concerns is sin, as appears from the following clause. He deceives himself as to its nature and consequences, its evil and aggravations, and he continues to do so until his iniquity be found to be hateful; till it be fully discovered, and appear in its magnitude and atrocious circumstances both to himself and others, by some awful divine judgment, such as that mentioned in the last verse of the Psalm: "There are the workers of iniquity fallen: they are cast down, and shall not be able to rise." He adduces this self deceit and continuance in it, as illustrating the truth of that judgment he had formed of the state of such a person: There is no fear of God before his eyes: for he flattereth himself in his own eyes. And surely the proof is incontrovertible. For a man under the bondage of sin would never flatter himself in his own eyes, were it not that God is not before them. The reason why he thinks so well of himself is, that God is not in all his thoughts. He hath cast off all fear about himself because he hath no fear of God. John Jamieson.
