The sermon focuses on 1 Corinthians 12, emphasizing the relationship between unity and diversity in the church. Paul teaches that spiritual gifts are distributed by God's sovereignty and serve the common good rather than individual status. The church is like a body—diverse in function yet unified in purpose. Each believer has a role and belongs, regardless of perceived strength or weakness. True humility and interdependence are essential, and weaker members should be honored, not overlooked. The passage warns against envy and division, reminding believers that God's design is intentional. The sermon challenges the church to embrace true diversity as defined by the word, serve each other selflessly, and demonstrate unity in Christ, which the world struggles to achieve.
