One principle theme of the book of Isaiah is the Servant of the Lord, often known as "The Suffering Servant" (see chapters 42-53). This Servant is a man who gave himself up for the salvation of his people. This Servant is the Lord Jesus Christ.
As you read about the wrath of God that is revealed against sin in the first part of this book, meditate on the curse that is justly applied to your life for your rebellion and disobedience of God's perfect law. And as you read about God's grace in the second part of this book, remember that his grace can be applied to you because someone else received God's justice in your place. Christ died for you. Isaiah 53:6 "We all, like sheep, have gone astray, each of us has turned to his own way; and the Lord has laid on him the iniquity of us all."
