The sermon centers on the transformative work of the Holy Spirit in the believer's life, emphasizing that victory over sin and death is already secured through Jesus Christ. Drawing heavily from 2 Corinthians 3, the message explores the shift from the Old Testament's veiled glory to the unveiled glory of the Spirit, leading to freedom, humility, and a growing understanding of God's perfection. It highlights the Spirit's role in drawing individuals to faith, renewing their minds, and shaping them into the image of Christ, ultimately leading to a progressive change from glory to glory as believers seek and depend on God's grace.
