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

1 Timothy 2:5 explicitly states, 'For there is one God, and one mediator between God and men, the man Christ Jesus.' This foundational truth underscores the importance of Christ’s unique role in salvation and reconciliation. Unlike Moses, who was a type of Christ, Jesus is the fulfillment of God's redemptive plan and the only means through which we can approach the Father. Hebrews 8:6 adds that Christ has obtained a more excellent ministry as the mediator of a better covenant, establishing that His priesthood and sacrifice surpass all preceding mediators and offerings. Therefore, understanding Christ as the exclusive mediator is crucial for grasping the essence of the Gospel and the assurance of salvation.
