Pastor Martin expounds Psalm 51:6, framing it as David's 'Confession of Contradiction' and 'Petition for Instruction.' He highlights the profound tension between God's desire for 'truth in the inward parts' and humanity's inherent depravity, as confessed by David. Martin argues that true conviction of sin arises from recognizing God's inflexible standard and its reach into the deepest recesses of the heart. The sermon culminates in the petition for God to impart wisdom, emphasizing utter dependence on the Holy Spirit to make truth a living, sanctifying principle rather than mere abstract propositions.
