Why is the concept of Christ being our mediator important for Christians?

The importance of Christ as our mediator lies in His unique role in establishing the New Covenant through His sacrificial death. Hebrews 9:15 states that He is the mediator of a new covenant, enabling those who are called to receive the promised eternal inheritance. This means that Christ not only intercedes on our behalf but also satisfies God’s justice through His death, allowing believers to approach God with confidence and without fear (Hebrews 4:16). By representing us before the throne of grace, Christ assures our standing before God, emphasizing the significance of His completed work and the guarantee of eternal life bestowed upon the elect.
