Why is the concept of mercy significant in Psalm 86?

In Psalm 86, the theme of mercy is central to the psalmist's prayer life. David repeatedly asks for God's mercy, demonstrating his understanding that he cannot stand before the Lord based on his own merits but relies entirely on God's graciousness. The pleas for mercy (verse 3) highlight both the seriousness of David's predicament and his faith in God's answering nature. This reliance on God's mercy resonates deeply with Reformed theology, which teaches that our salvation and preservation are dependent not on our righteousness but entirely on God's grace through Christ. Furthermore, recognizing our need for mercy fosters a sincere approach to prayer, aligning our hearts with God's willingness to forgive and restore (Psalm 86:5).
