What does Isaiah 53 say about Christ's suffering?

Isaiah 53 powerfully communicates the suffering of Christ, stating that He shall bear our iniquities and endure grief for His people. Verses like Isaiah 53:5 proclaim that He was wounded for our transgressions and that His suffering was purposeful and redemptive. This chapter underlines the reality that Christ's suffering was not in vain but was designed to accomplish the salvation of all whom the Father has given Him. It affirms the doctrine of penal substitution, where Jesus takes our place, bearing the full weight of sin's penalty.
