This 23rd book of the Bible leads us into the next major collection of books, the prophetic books. The prophetic books are divided into two major sections: Major Prophets (Isaiah-Daniel) and Minor Prophets (Hosea-Malachi). Their designation as major and minor does not have to do with their importance, but rather their size.
Isaiah is one of the most important books of prophecy in the Old Testament, and is quoted a bunch in the New Testament. The book has two major themes: Judgment and Future Expectation.
The nation of Israel had failed God over and over again, and now has reached a point of no return and judgment will come. The mission God had given them was to be a beacon and light to the entire world about His goodness and mercy. Instead of magnifying the Lord, they constantly questioned His goodness and power.
In order to accomplish His purposes, God has to purify Israel. His intentions for sending Assyria and Babylon was not evil vindication, but rather a desire to remove the dross and evil from His people.
Isaiah chapter 6, is a major chapter in the book. Here we see Isaiah transported to a place where he sees God’s majesty and highness. The Godly king Uzziah has just died, and Isaiah sees the Lord high and lifted up. Angelic beings cry out HOLY, HOLY, HOLY, and the scene overwhelms Isaiah. He confesses the sins of Israel and him personally. He sees clearly how just and righteous God is to judge Israel. An angelic being comes with a hot coal, and instead of destroying Isaiah, it purifies him.
God tells Isaiah that he will have a failing ministry. He will warn of Judgment, but this will only harden the people’s heart… they will not repent. So, you might be wondering where the hope and future expectation is.
The book of Isaiah, more than any other book, develops the idea of the New Jerusalem. A perfect kingdom from which God Himself shall reign with perfection and justice. Isaiah gives us this promise in chapter 7 when he tell us about Emmanuel. Again this shadowy picture is seen again in Isaiah 53, when the crucifixion of Christ is given in exacting detail.
The truth Isaiah points to is the death of Christ, and future perfect kingdom in New Jerusalem. It is a wonderful book of hope and promise.
You will enjoy the 66 chapters of this book which show judgment and hope.
