What does the Bible say about substitution in Christ's sacrifice?

Isaiah 53 provides a profound prophecy of the Messiah's work as the suffering servant who would bear the iniquities of God's people. In verse four, it states that 'Surely he hath borne our griefs and carried our sorrows,' indicating that Christ took upon Himself the sins and sufferings of His elect. This chapter illustrates the nature of substitutionary atonement, where Christ suffered in the place of sinners, highlighting the depth of His love and the gravity of our sin. Furthermore, verses five and six emphasize that He was wounded 'for our transgressions' and that 'the Lord hath laid on him the iniquity of us all,' demonstrating that Christ's death was specifically for His chosen people, securing their redemption.
