What does it mean for Christ to be our mediator?

In Reformed theology, Christ's role as mediator is fundamentally about reconciliation between God and His people. Hebrews 9:15 presents Christ as the mediator of the new covenant, affirming that through His death, He redeems those under the first covenant. As our mediator, Jesus advocates for us before the Father, representing humanity while simultaneously being fully divine. This duality ensures that His atoning sacrifice is adequate and effective to cover the sins of His people. Hence, Christ's mediatorial work is vital because it assures believers of their acceptance before God, providing confidence in the face of divine judgment and enabling believers to worship God freely.
