The theme of the book of Isaiah is simply this, God wants to have fellowship with all of mankind. Isaiah warns the kingdoms of Israel and Judah and the surrounding nations of impending judgment and destruction because of their sins of pride, idolatry, and oppression of the poor. We have a historical interlude that leads to Judah’s captivity by Babylon and God’s efforts to get the attention of His children so they will return to Him.
We also read a lot about the Messiah and the Good News He will bring. Isaiah prophesied a lot about the Christ, in fact, he prophesied about Christ more than any other Old Testament prophet, and he is quoted in the New Testament more than any other prophet. There are about fifty-four New Testament quotations of Isaiah.
