How do we know Jesus is the Surety of His people?

Jesus is identified as the Surety of His people through His mission detailed in Scripture, where He takes on the responsibility of redeeming humanity through His sacrifice. His work on the cross is central to this, displaying His commitment to fulfill the requirements of the law on behalf of sinners. The authority given by the Father reinforces this position, as seen in His ability to promise eternal life and living water to those who come to Him. Understanding Jesus as the Surety strengthens our faith, reminding us that His suffering and sacrifice were specifically for our benefit, providing assurance of grace and acceptance with God.
