How does Jesus' death fulfill Old Testament Scriptures?

In John 19:28, it is noted that Jesus' actions while on the cross fulfilled the Old Testament Scriptures, demonstrating how His life and death were a fulfillment of prophecy. Throughout the Gospels, Jesus often refers back to the Scriptures, asserting that they testify of Him. This seamless connection highlights that every promise made in the Old Testament regarding salvation and the coming Messiah finds its culmination in Christ's sacrificial death. Moreover, Paul emphasizes in Acts 13:32 that what God promised is fulfilled in Jesus, providing a robust theological foundation for understanding Jesus as the fulfillment of the entire redemptive narrative presented in Scripture.
