Christ's substitution is validated through His perfect fulfillment of the law and His sacrificial death.
Christ's role as our substitute is central to the gospel. The biblical doctrine of substitution asserts that Christ entered our place as both the perfect high priest and the sacrificial lamb. He fulfilled the law by obeying it completely and satisfying God's justice through His sacrificial death. As noted in Hebrews 7:26-27, He is the holy and perfect high priest, who offered Himself once for the sins of His people. This notion of substitution is rooted in biblical typology, where the Old Testament sacrifices prefigure Christ's ultimate sacrifice for sin, confirming that He bore the iniquity of God's elect, making salvation certain for those who trust in Him.
