Substitutionary atonement is affirmed through scripture, especially in passages like Isaiah 53 and the New Testament affirmations of Christ's sacrificial death.
Substitutionary atonement is supported throughout both the Old and New Testaments. Isaiah 53 clearly articulates that the Messiah would bear the sins of many, indicating that the atoning work of Christ was foreseen long before His incarnation. In the New Testament, assertions such as in Romans 3:24-26 show that God had to be both just and the justifier of the one who has faith in Jesus. This illustrates the idea that Christ's blood was shed as a substitute for our sins, thereby satisfying God's holy justice while allowing Him to extend mercy to sinners.
