Why is the mediation of Christ important for Christians?

Christ's role as our mediator is fundamental for Christians because it establishes our peace with God. Romans 5:1 says, 'Therefore, being justified by faith, we have peace with God through our Lord Jesus Christ.' By taking on our sins and the punishment they deserve, Christ not only intercedes on our behalf but also assures us of our acceptance before God. In doing so, He fulfills the law’s demands and secures our eternal inheritance. His ongoing intercession proves that we are continually sustained in our relationship with the Father, emphasizing that our hope rests not on our works, but entirely on what He has accomplished for us.
