Here is an outline of Isaiah taken from an online commentary which may be found at:
www.christadelphianbooks.org/agora/comm/23_isa/index.html
Author: Isaiah son of Amoz
Time: 740 – 690 BC
Summary: Isaiah ministered in the southern kingdom of Judah during the reigns of Uzziah, Jotham, Ahaz and Hezekiah. He deals with the coming judgment on Judah due to its idolatry and apostasy. He urges the kings and the people to put their trust in God rather than in alliances with other nations. He comforts his people with the realization that God loves those who are faithful to Him and keep His commandments. He speaks of the future Messiah who would come to redeem the nation and restore the Kingdom.
Key verse: "For to us a child is born, to us a son is given, and the government will be on his shoulders. And he will be called Wonderful Counsellor, Mighty God, Everlasting Father, Prince of Peace" (Isa 9:6).
