Why is Jesus as the mediator of the new covenant important for Christians?

The importance of Jesus as the mediator of the new covenant cannot be overstated. Hebrews 9:15 highlights that through His death, Christ redeems those who are called, granting them the promise of eternal inheritance. This contrasts sharply with Moses, who mediated the old covenant based on the law that depended on human obedience. The new covenant, however, is founded on grace and the finished work of Christ, establishing a relationship with God that is secure and unbreakable. By shedding His blood, Jesus fulfilled the requirements of the old covenant and established a new way for sinners to come to God. This transformation from law to grace is pivotal as it reassures believers that salvation is not dependent on their performance but on Christ's righteousness. Such a relationship transforms the believer's experience, moving from condemnation to acceptance, from fear to assurance.
