How do we know the Mediator of the New Covenant is Christ?

Scriptural evidence clearly identifies Jesus as the Mediator of the New Covenant. In Hebrews 8:6, it is explicitly stated that Jesus mediates a superior covenant established on better promises. His role as Mediator is underscored by His sacrificial death, which is described in Hebrews 12:24, where His blood is said to speak better things than that of Abel. Furthermore, Christ's unique position is affirmed through His fulfillment of the Law and Prophets, where He becomes the ultimate sacrifice that reconciles believers to God. John 1:1-4 also reinforces this by emphasizing that the Word was with God and was God, affirming Christ's divine nature and authority. His continual intercession for believers positions Him as the sole mediator through whom believers approach the Father.
