The passage from 2 Corinthians discusses the glory of the new covenant in contrast to the old covenant, emphasizing that while the old law could condemn, it lacked the power to empower believers. It highlights that only through Christ can the veil that covers hearts be removed, allowing for true transformation and reflection of God's glory. Believers are encouraged to grow in Christ's image and share in His glory through the Spirit, motivating them to reflect on their relationship with God and the legacy they wish to leave.
