Isaiah’s own testimony—that his revelations specifically address the end-time; that they foretell the end from the beginning; that Israel’s ancient history consists of a series of types or precedents that foreshadow things to come; and so forth—clearly define his book as centrally important to understanding God’s dealings in human history, past, present, and future. But the book’s second component—a covenant theology that covers the entire field of peoples’ relationships to Israel’s God—makes it most relevant to a people of God in any age.
The book’s unsealing based on the discovery of literary tools that uncover its layered meanings itself tells us it was reserved to be published and understood in the day its prophecies would be fulfilled. In other words, God has held the prophetic message of this book in reserve in order to bring it forth to those to whom it would most apply—his end-time people. As Isaiah explains, it would fill the void of divine revelation and knowledge that was predicted to prevail in that very time when other prophetic voices would falter and be stilled.
On the other hand, only those who search the words of Isaiah by utilizing the simple literary tools now available can comprehend its importance to today, when its prophecies have begun being fulfilled. So enormous is the paradigm shift of understanding Isaiah for those beholden to current religious paradigms, however, that many persons forgo making the attempt entirely or get carried away with their new knowledge, thus bringing about the very separation among his end-time people that Isaiah predicts God will bring about.
Never mind the prophecies of bygone events;Isaiah 43:18-19
do not dwell on things of the past.
See, I do a new thing; it is now springing up.
