What does Isaiah 53 teach about the purpose of Christ's suffering?

Isaiah 53 provides a profound insight into the purpose of Christ's suffering by explicitly stating that He was 'wounded for our transgressions' and 'bruised for our iniquities' (Isaiah 53:5). This chapter conveys the depth of Christ’s sacrificial love, illustrating that His affliction was not for His own failings but for the failings of humanity. His suffering was central to the gospel message, whereby through His wounds we are spiritually healed, embodying the doctrine of substitutionary atonement. It shows that Christ did not merely endure suffering; He endured it on behalf of those He came to save, fulfilling God’s righteous requirement and enabling believers to be reconciled to God through faith in Him.
