The sermon centers on the call to adopt the mind of Christ, exemplified in His incarnation, humility, and self-sacrificial love, as described in Philippians 2:5–8. It emphasizes that true Christian living requires a radical transformation of the inner man—mind, heart, and will—through the renewing of the mind by Scripture, enabling believers to reject self-centeredness and embrace servant-hearted humility. Drawing from Christ's descent from divine glory to a manger, the sermon contrasts the world's me-focused culture with the gospel's call to self-denial, service, and sacrificial love. It underscores that this spiritual renewal is not achieved by human effort alone but through the indwelling Holy Spirit, who renews the believer's thoughts and shapes their actions. Ultimately, the sermon calls the church to live as a counter-cultural community, reflecting Christ's mind in daily life, worship, and witness, so that His name may be glorified in all things.
