The sermon centres on the profound truth of God's eternal sovereignty and holy omniscience, drawing from Psalm 90 to reflect on the fleeting nature of human life compared to God's everlasting existence. It emphasises that no sin—whether public or secret—can be hidden from God, who sees all with perfect clarity, as light exposes darkness and reveals every iniquity before His countenance. While this reality is sobering, the message pivots to the grace of God, who, though just and holy, has provided salvation through Christ, casting our sins behind His back and remembering them no more. The sermon calls believers to repentance, humility, and worship, urging them to live with eternal perspective, knowing that though life is brief and fragile like a flower, those in Christ are secure in His presence and freed from the burden of guilt. Ultimately, it is a call to draw near to God in prayer and praise, recognizing both His holiness and His mercy.
