What does the Bible say about Christ's suffering for our sins?

Isaiah 53:5 reveals the foundational truth of Christ's redemptive work, stating that 'He was wounded for our transgressions, He was bruised for our iniquities.' This passage emphasizes the substitutionary nature of Christ's suffering. Christ's wounds serve not only as a record of His physical pain but as a testament to His role as our substitute who bears the punishment for sin on our behalf. The verses convey that our healing and peace are procured through His suffering, illustrating the profound mystery of God's grace where the innocent suffers for the guilty. This is a central tenet of Reformed theology, affirming that Christ's atoning sacrifice addresses the guilt of all sinners, fulfilling the wrath of God against sin.
