How do we know Christ is the only mediator between God and man?

The reaffirmation of Christ as the sole mediator comes from 1 Timothy 2:5, which states, 'For there is one God, and one mediator between God and men, the man Christ Jesus.' This declaration combats pervasive false teachings that propose additional mediators. Paul emphasizes that our justification and reconciliation to God occur solely through the person and work of Christ. With the Gospel continually affirming the singularity of this path, believers are assured that their relationship with God hinges entirely on faith in the sufficiency of Christ's redemptive work.
