The sermon centers on the profound paradox of God's character revealed in Exodus 34:6–7—the tension between His infinite mercy and His unyielding justice. It explores how God, described as merciful, gracious, and slow to anger, yet declares that He will by no means clear the guilty, highlighting the impossibility of reconciling holiness with sin without divine intervention. The resolution to this riddle is found in the person and work of Jesus Christ, who bore the penalty for sin, satisfying divine justice while extending mercy to those who trust in Him. The preacher emphasizes that this truth, though humbling and awe-inspiring, calls for an immediate response of worship, as seen in Moses' act of bowing in reverence. The sermon culminates in a call to personal repentance and faith, inviting all to respond with gratitude and adoration, grounded in the redemptive work of Christ and affirmed through communal worship of Psalm 103.
