Why is the concept of Christ being our mediator important?

The role of Christ as our mediator is crucial for understanding our relationship with God. Hebrews 9:15 states that Christ is the mediator of the New Testament, facilitating our reconciliation with God through His death. Without this mediation, our sins would stand between us and God, leaving us condemned. Christ's sacrifice satisfies God's justice and allows us to approach Him in faith. This means that in Christ, we have direct access to the Father and can be assured of His mercy and love toward us. The completeness of Christ's work means that we no longer have to rely on our own righteousness or works, but rather on His finished work.
