This sermon explores how the gospel transforms not just individual beliefs but entire worldviews and ways of living. Through examining 1 Corinthians 1:2-9, the message reveals how the early Corinthian church struggled to let the gospel reshape their lives in a culture marked by sexual immorality, idolatry, wealth, competition, and pluralism. Paul addresses them as "sanctified" and "called to be holy"—set apart for God's purposes despite living in a morally corrupt city. The sermon challenges modern believers to recognize how their own culture shapes them and to allow Jesus to reframe every aspect of life: power, freedom, relationships, sexuality, and community. The central theological point is that Christians are "different now"—not called to be more religious, but to live into their new identity in Christ, being holy people set apart for God's purposes while remaining engaged in their culture.
