How do we know God makes us glad?

The psalmist in Psalm 92 confesses that his gladness comes from the work of the Lord, not from his own righteousness or efforts. This aligns with the broader biblical teaching that our best works are insufficient and akin to 'filthy rags' in the sight of God. Acknowledging that joy comes through God's promises and His fulfillment brings peace and gladness. The assurance that God's faithfulness brings new mercies every day is what truly uplifts the believer, demonstrating that it is His work, not our human attempts, that brings genuine joy.
