What does it mean that Christ's suffering was substitutionary?

The concept of substitutionary suffering refers to Christ bearing the sins of His people in His own body on the cross. According to 1 Peter 2:24, He took the punishment we deserved, fulfilling God's justice on our behalf. This means that Christ not only represented us but actively took our place, ensuring that our sins are judged in Him rather than against us. This substitution is the foundation of redemption, as it indicates that through His death, believers are liberated from condemnation and enabled to live in righteousness. It underscores the core of the gospel message: our healing and restoration come through Christ's vicarious suffering.
