Psalm 90 is presented as a profound call to honest reflection on the brevity and fragility of life, not as a source of despair but as a pathway to wisdom and divine intimacy. Centered on the reality of human transience and the just wrath of God due to sin, the psalm confronts the pain of loss, failure, and mortality, yet anchors hope in God’s eternal nature as our dwelling place. Through the lens of communal lament and the redemptive work of Christ, who bore our sins and conquered death, the sermon reveals that true fulfillment comes not in self-directed resolutions or worldly achievements, but in trusting Christ as our refuge and living each day in anticipation of eternal joy. The call to ‘number our days’ is ultimately an invitation to repent, find satisfaction in God’s steadfast love, and labor in faith, knowing that in Christ, even suffering is shaped for glory and our fleeting days are secured in everlasting life.
