Psalm 52. Psalm 51 was David's response to correction of his sin with Bathsheba. If you are in sin and doing religious activities, God does not accept it. Psalm 52 is mostly negative of when David was running from Saul. King Saul did not want David to be the next king, so Saul was not really fighting David but rather was fighting God. All sin is rebellion against God. God's goodness never causes you to boast in evil. God's goodness is continual and will never bless those doing evil. Your mouth leads the direction of your life. The speech of the wicked will be boastful, untruthful, and nasty. It may seem like they have the upperhand and that their boasts will come true, but then we remember "Oh wait, God." God calls them to repentance. He gives us multiple opportunities to confess our sin. If rejected, He lets you store up your sin to destruction. Those who repent and walk in the Lord have forever in the presence of the Lord.
