What does the Bible say about the mediator Jesus Christ?

In 1 Timothy 2:5-6, the Apostle Paul emphasizes the unique mediatorial role of Jesus Christ, stating that there is one God and one mediator between God and men—the man Christ Jesus, who gave Himself a ransom for all. This passage highlights the greatness of Christ’s redemptive sacrifice, and His work fulfills the requirements of divine justice by paying the debt that sinners owe to God's holy law. As our Mediator, Christ not only advocates for us but also embodies redemption itself, enabling believers to approach God confidently.
