Psalm 14:1, 53:1 “The fool says in his heart, “There is no God.”
Fool “A person with little or no judgment, common sense, wisdom, a silly person; simpleton.”
An impious person who has no perception of ethical or religious truth. The meaning of this text is not “unintelligent people do not believe in God, but rather “sinful people do not believe in God”. It is a terrible thing to deny God, and a denial of God is often accomplished by a corrupt lifestyle. This Scripture goes on to list some other characteristics of the irreligious. “They are corrupt; their deeds are vile; there is no one who does good.” Psalm 14:1-7 is a study of the depravity of mankind.
