How do we know Jesus acts as our surety and mediator?

The concept of Jesus as our surety and mediator is grounded in His sacrificial role for His people. As described in the sermon, Jesus fulfills the role of a surety by bearing the obligations of His people, ensuring that justice is satisfied on their behalf. This is visually represented through Old Testament types, such as Judah serving as a surety for Benjamin. Moreover, Jesus intercedes for believers as the ultimate mediator, exemplified through the role of Moses interceding for the Israelites. Christ stands before God, offering His righteousness and prayer, ensuring that our requests are heard. He is both fully divine and fully human, making Him perfectly suited for this role, and it is through His mediatorial work that believers can confidently approach the throne of grace.
