The sermon centers on the urgent need to reclaim God's glory as the ultimate purpose of life, confronting the pervasive idolatry of self and cultural worldviews that exalt human autonomy over divine authority. Drawing from Psalm 115, it emphasizes that true worship is not about human achievement or cultural narratives, but about recognizing God's sovereign power, faithfulness, and exclusive worth, as He alone does all that He pleases in heaven. The message warns that modern idols—such as fame, pleasure, money, and control—deceive by promising freedom while enslaving the soul, transforming worshippers into lifeless, spiritually hardened images of themselves. In contrast, the Christian life is defined by a biblical worldview that finds meaning in God's objective truth, grace, and the transformative work of Christ, calling believers to live in humble obedience, gentle courtesy, and selfless remembrance of Christ's sacrifice. As the congregation prepares to observe the Lord's Supper, the call is clear: to glorify God supremely, regardless of circumstance, and to reject all false gods that steal the soul's true allegiance.
