Why is the concept of the New Covenant important for Christians?

The New Covenant carries immense significance for Christians as it redefines our relationship with God, shifting from a works-based system to one grounded in grace and faith. Galatians 3:12 highlights that the law is not of faith; it requires performance that no one can perfectly achieve. In contrast, the New Covenant assures believers that their sins are forgiven and that they are accepted based on Christ's righteousness alone. This understanding liberates Christians from the fear of judgment based on performance and invites them to live joyfully in the grace of God, empowered by the Holy Spirit to pursue holiness.
