What does the Bible say about restoration in Isaiah?

In Isaiah 42:22-43:5, the prophet describes a people who are robbed and in need of restoration. He highlights their spiritual plight and the failure to obey God's laws, particularly the law of restitution, showing that they have sinned against God profoundly. The call for restoration directly points to the work of Christ, who fulfills this need by making double restitution for His people’s sins. As Christ Himself declared, 'I restored that which I took not away' (Psalm 69:4), meaning He paid the price for our sins and provided us with eternal righteousness and redemption.
