Every book of the Bible is important for us to know. Every book of the Bible contributes to doctrine and to theology. Every book of the Bible is inspired by God and is necessary for reproof, correction, and training in righteousness (2 Tim.3:16). But the Book of Isaiah has some unique qualities that make it especially important to understand. Ephesians 2:20 tells us that the church has been built upon the foundation of the apostles and the prophets while Romans 16:25-26 tells us that we are strengthened in our faith according to the revelation of the prophetic scriptures. The message of the Old Testament prophets plays an integral part in the faith of the New Testament believer. With this in mind, it is important to note that Isaiah is the most often quoted prophetic book in the New Testament.
