How do we know Jesus is the blood substitute mentioned in the Bible?

The identification of Jesus as the blood substitute is rooted in biblical prophecy and the sacrificial system laid down in the Old Testament. Blood must be shed for the remission of sins (Hebrews 9:22), and Christ's death on the cross is the ultimate fulfillment of this requirement. As mentioned in Luke 24:27, Christ explained how the Scriptures testify about Him, culminating in His atoning work. This comes together in the genealogy of 1 Chronicles, where names illustrate themes of sacrifice and redemption, with Jesus being the ultimate blood sacrifice provided by God.
