What does the Bible say about the mediator of the covenant?

In the New Testament, particularly in the book of Hebrews, we learn that Jesus serves as the mediator of a new and better covenant. Unlike the covenant of works exemplified by Moses, which required perfect obedience and ultimately led to condemnation, the covenant of grace highlights Jesus’ perfect fulfillment of the law on behalf of His people. As our mediator, He reconciles us with God through His sacrificial death, ensuring that our acceptance before God is based on His righteousness rather than our own. This is a pivotal aspect of sovereign grace theology, emphasizing that we are saved solely by God's grace, mediated through Christ.
