Why is Christ the only mediator between God and man?

The exclusivity of Christ as our mediator is foundational to Christian faith. 1 Timothy 2:5 declares that there is one God and one mediator between God and men, the man Christ Jesus. This means that no other mediators or additional works are necessary for our salvation. Christ's unique role is underscored by His sacrificial death, which fully satisfies God's justice. His intercession ensures that our standing before God is secure, as He represents us as our advocate (Romans 8:34). Believers have direct access to God through Christ, who alone bridges the gap created by sin.
