David describeth the corruption of a natural man.
Psalms 14:1 Unto the end, a psalm for David. The fool hath said in his heart: There is no God. They are corrupt, and are become abominable in their ways: there is none that doth good, no not one. Psalms 14:2 The Lord hath looked down from heaven upon the children of men, to see if there be any that understand and seek God. Psalms 14:3 They are all gone aside, they are become unprofitable together: there is none that doth good: no not one. Their throat is an open sepulchre; with their tongues they acted deceitfully: the poison of asps is under their lips. Their mouth is full of cursing and bitterness; their feet are swift to shed blood. Destruction and unhappiness in their ways; and the way of peace they have not known: there is no fear of God before their eyes.
He convinceth the wicked by the light of their conscience.
Psalms 14:4 Shall not all they know that work iniquity, who devour my people as they eat bread? Psalms 14:5 They have not called upon the Lord: there have they trembled for fear, where there was no fear. Psalms 14:6 For the Lord is in the just generation: you have confounded the counsel of the poor man; but the Lord is his hope.
He glorieth in the salvation of God.
Psalms 14:7 Who shall give out of Sion the salvation of Israel? when the Lord shall have turned away the captivity of his people, Jacob shall rejoice, and Israel shall be glad.
