Why is Christ's mediatorial work important for Christians?

The mediatorial work of Christ is foundational for Christianity, as it depicts Him as the bridge between sinful humanity and a holy God. In His threefold office as prophet, priest, and king, Christ fulfills all necessary roles to secure the salvation of His people. As our Prophet, He reveals God to us; as our Priest, He offers Himself as the perfect sacrifice for atonement; and as our King, He governs and protects His kingdom. This means that through His mediatorship, believers are assured of forgiveness, ongoing intercession, and eternal hope. As Romans 8:34 affirms, 'It is Christ that died, yea rather, that is risen again, who is even at the right hand of God, who also maketh intercession for us,' highlighting the critical nature of His mediatorial role.
