Why is the concept of Christ as mediator important for Christians?

The concept of Christ as mediator is foundational in Reformed theology, underscoring His unique role as the God-man who reconciles humanity to God. Jesus embodies the perfect mediator because He is both fully divine and fully human, allowing Him to understand the depth of human sin while also possessing the power to atone for that sin. His work as mediator is crucial, as it was through His sacrificial death that believers are justified. As mentioned in the sermon, Christ fulfills this role, making it possible for us to have direct access to God, effectively interceding on our behalf, and demonstrating God's plan for salvation as established before the foundation of the world.
