How does Jesus secure salvation for His people?

The sermon conveys that Jesus secures salvation through His perfect life and sacrificial death, specifically as the atoning substitute for His people. The message articulates that He did not come merely to make salvation a possibility; rather, He accomplished it definitively by shedding His blood as the payment for sin. This act of redemption is rooted in God's sovereign plan where Christ was chosen to be the Lamb of God before the foundation of the world. Therefore, the certainty of Christ's mission is emphasized by the statement that He shall save—not may save—describing an act of guaranteed efficacy that fulfills God's justice and secures eternal life for His people.
