53:7-12 In the Old Testament, people offered animals as sacrifices for their sins. Here, the sinless servant of the Lord offers himself for our sins. He is the Lamb (53:7) offered for the sins of all people (John 1:29; Revelation 5:6-14). The Messiah suffered for our sakes, bearing our sins to make us acceptable to God. What can we say to such love? How will we respond to him?
53:11 "My righteous servant will justify many" tells of the enormous family of believers who will become righteous, not by their own works, but my the Messiah's great work on the cross. They are justified because they have claimed Christ, the righteous servant, as their Savior and Lord (see Romans 10:9; 2 Corinthians 5:21). Their life of sin is stripped away, and they are clothed with Christ's goodness (Ephesians 4:22-24).
