This psalm reminds us of the reality that there really is no good and bad people. Evil runs through all of us and our hearts are wicked and depraved. All of us are capable of great sin. Put aside your pride and confess your sins to God daily and ask for his mercy.
There Is None Who Does Good
To the choirmaster: according to Mahalath. A Maskil[a] of David.
53 The fool says in his heart, “There is no God.” They are corrupt, doing abominable iniquity; there is none who does good.
2 God looks down from heaven on the children of man to see if there are any who understand,[b] who seek after God.
3 They have all fallen away; together they have become corrupt; there is none who does good, not even one.
4 Have those who work evil no knowledge, who eat up my people as they eat bread, and do not call upon God?
5 There they are, in great terror, where there is no terror! For God scatters the bones of him who encamps against you; you put them to shame, for God has rejected them.
6 Oh, that salvation for Israel would come out of Zion! When God restores the fortunes of his people, let Jacob rejoice, let Israel be glad.
