Why is the concept of Christ as the mediator important?

The importance of Christ as mediator lies in His unique nature as both divine and human. 1 Timothy 2:5 emphasizes that there is one God and one mediator between God and man, the man Christ Jesus. As the second person of the Trinity, Christ not only represents God to humanity but also humanity to God. His role as mediator is crucial because it establishes the only way through which sinners can approach a holy God. In a sovereign grace framework, this mediation is not merely symbolic but actualizes salvation for the elect, providing assurance and peace before the judgment seat of God.
