How does the concept of new creation relate to salvation?

The idea of new creation is central to understanding salvation in Reformed theology. When a sinner is saved, Scripture indicates that they become a new creation (2 Corinthians 5:17). This transformation is not merely a reforming of the old but a complete regeneration by the Holy Spirit. Just as God spoke light into the darkness during creation, He speaks spiritual life into the hearts of those whom He saves. This new birth is a divine act, accomplished by God's Spirit, and signifies a break from their previous state of darkness into the light of Christ. The new creation reflects a true change in nature and identity, where the believer is equipped to walk in newness of life, reflecting God's righteousness and holiness through Christ.
