How do we know the doctrine of Christ as Mediator is true?

The belief in Jesus Christ as the Mediator between God and man is firmly rooted in both the Old and New Testaments. In 1 Timothy 2:5, Scripture declares, 'For there is one God and one mediator between God and mankind, the man Christ Jesus.' This foundational text emphasizes that Jesus serves as the sole mediator, bridging the gap created by sin and making access to God possible for all who believe. The prophetic texts in the Old Testament foreshadow this role, establishing that God's plan for redemption involved a chosen Servant who would intercede on behalf of His people (Isaiah 53).

Moreover, throughout His ministry on earth, Jesus acted as a mediator by teaching about the Kingdom of God, healing the sick, and ultimately laying down His life for the sins of humanity. His resurrection from the dead and ascension into heaven serve as divine affirmations of His mediatorial position, as He now lives to intercede for believers (Romans 8:34). Consequently, the doctrine that Christ serves as our Mediator is substantiated through Scripture and His redemptive works, providing assurance to believers that they can approach the throne of grace with confidence.
