The events at the end of the last chapter are Millenial. So, then, are the events described in this chapter. Isaiah is a Millenialist. If he is not speaking of the Messiah or the destruction of the wicked, the glory of the Millenium is his next most likely topic.
Accordingly, the theme of Isaiah 54 is that the House of Israel, or the people of the Lord, will be redeemed from every pain, problem, fear, terror, disgrace, oppression, hardship, or reproach. In the Millenium, the Lord will more than make up for any previous suffering.
