According to Isaiah 53:8, why does the servant of the Lord suffer? Let's find out.
There is no indication in verse 8 that the servant of the Lord suffers to atone for the sins of others. What this verse states is that he suffers as a result of the misdeeds of others, who treat him unfairly and unjustly. Hence, the conclusion of the verse, in which the enemies of the servant admit responsibility for the cruel treatment they have meted out to him.
This is the confession of the Gentile spokesperson, who now expresses the Gentile realization that it was they and their people who deserved to suffer the humiliation inflicted on the servant of the Lord, as admitted in verses 4-6. In short, the servant's enemies admit that his suffering stemmed from their own sinful imposition of hardships upon him: "From the transgression of my people there has been affliction to him [them]." The servant of the Lord suffers not on behalf of others' sins but because of the things that sinful men do to him.
