How do we know that Christ's mediatorial role is necessary?

The necessity of Christ's mediatorial role is evident through scripture that outlines the condition of humanity in sin. Since all have sinned and fall short of the glory of God, it is impossible for us to approach Him without an intermediary who satisfies His justice. The Bible expresses that sin creates a relational breach that cannot be mended by our efforts. Therefore, Christ steps in as the mediator who bridges this gap. Through His death and resurrection, He serves both as the sacrifice for sins and the intercessor for His people, ensuring that their relationship with God is restored. Without this role, believers would remain alienated from God, highlighting the critical nature of Christ's work as the unique mediator.
