This and the additional chapters of Isaiah offers comfort and encouragement to a people coming out of living under the terrible condition of exile for almost 70 years. In this chapter (and subsequent chapters) God gives Isaiah a vision to share with the people of His, Everlasting Comfort, his Everlasting Word and His Everlasting Strength that no matter how hopeless, depressing and discouraging things get we have got to be "Like Eagles" and soar above our difficulties.
