In this sermon from Psalm 26, Pastor Rockhill draws on the familiar image of a final exam to confront every hearer with the reality of standing before Christ in judgment. Just as David boldly invites God to vindicate, examine, and try his heart, so believers are called to welcome God's searching scrutiny now rather than dread it on the last great day described in 2 Corinthians 5:10. Pastor Rockhill walks through David's testimony, showing what a passing life looks like: keeping God's covenant lovingkindness ever before the eyes, walking obediently in God's truth, separating from the wicked while remaining a witness in the world, seeking cleansing from sin, offering thanksgiving, and loving the house and people of God. Yet the central burden is that none of these works can save. David's plea, "Redeem me and be merciful to me," reminds us that our righteousness is but filthy rags. The doctrine pressed home is justification by grace alone through faith in Christ alone. Only Jesus walked in perfect integrity without slipping, and His vindication in the resurrection secures the believer's standing before God, men, and angels. Pastor Rockhill closes with a tender, urgent application: examine yourself daily through the Word, the fellowship of the saints, and the trials God sends, and rest wholly in the perfect righteousness of Christ. Those who trust Him now will hear Him say on that day, "This one is mine," and will not be disappointed.
