Reformed worship is defined by its exclusive focus on Christ, grounded in Scripture, and centered on His sovereign authority and redemptive work. It rejects man-centered practices, whether through emotionalism, self-expression, or human tradition, and instead exalts Christ in every element of worship—preaching, prayer, praise, and the sacraments—because He is the only mediator, the object of faith, and the foundation of true worship. The sermon emphasizes that Christ must be the preeminent subject of every act of worship, not merely mentioned but magnified as Lord, Savior, and Redeemer, with all Scripture, song, prayer, and sacramental practice pointing to His finished work on the cross. This Christ-centered worship is not optional but essential, as it preserves the gospel, corrects false worship, and aligns the church with God's revealed will, ensuring that every aspect of worship glorifies Christ and prepares believers for eternal fellowship with Him.
