What does the Bible say about substitution and satisfaction?

In Isaiah 53, substitution and satisfaction are beautifully portrayed through the suffering servant, the Lord Jesus Christ. The text emphasizes that Christ is God's righteous servant who bears the iniquities of His people (Isaiah 53:11). This concept of substitution reveals that our sins were laid upon Him, leading to His suffering and the satisfaction of God’s holy justice. The travail of His soul was the divine suffering necessary to fulfill God's law and bring about reconciliation between God and man.

Moreover, the idea of satisfaction stems from God's acceptance of Christ’s sacrificial death as a just payment for the sins of many. In verses 5 and 10, it is made clear that Christ was wounded for our transgressions and that it pleased the Lord to bruise Him because of what He accomplished on behalf of God’s elect. Thus, substitution refers to Christ's role as our sin-bearer, and satisfaction signifies that God's justice has been fully met through His sacrifice.
