This world is corrupted and filled with wickedness. Psalm 10 addresses the wickedness of this world and the destruction that such evil brings, particularly to the weak and vulnerable. However, you must be careful not to assume that the wickedness exposed in Psalm 10 applies to someone else. This psalm does not confront the classical atheism of those who openly reject the existence of God but functional atheism of living as though there is no God.
The psalm calls believers not to settle for the things of this world but to long for the kingdom to come when the king who is king forever will fully reign.
And while there is an opportunity, it beckons all to bow the knee, confess Jesus as Lord, and surrender yourself to the king who is king forever.
