The fool said in his heart, “There is no God.” They became corrupt and were defiled in their deeds. there is no one who does good.
“The fool” here is the one who, in his heart and life, rejects God’s rule and does not want to live under His authority. The words “There is no God” can express not only open unbelief, but also a way of life as though God does not see, does not judge, and His will has no significance. From that inner rejection comes the corruption of conduct. The psalmist shows that the root of sin is in the heart, and deeds are its fruit. The phrase “There is none who does good” emphasizes the universal depth of human sinfulness, not the idea that every person commits every possible evil. The apostle Paul uses these very words to show that all people are under sin and need God’s grace (Romans 3:10–12). Therefore, the verse not only condemns open godlessness, but also calls every person to examine whether, in his life, he truly accepts God’s rule.
