A New Testament book that is particularly related to prophetic subjects is the book of Revelation. Now you must understand that there are various views concerning Revelation. John Calvin was a great scholar and prolific writer, yet he never wrote a commentary on Revelation. Martin Luther was extremely unhappy with Revelation, and when you begin to read Revelation, you may share Luther's unhappiness, because Revelation is filled with symbolism. We read about horns, smoke, beasts, thunder, noise, seals, vials, and trumpets, and it is hard to know what they all mean.
Revelation is a difficult book to understand.
There are various views of how to interpret this difficult book. First there is the spiritual view, meaning that Revelation gives us certain spiritual principles which are applicable to the church throughout the ages. Those who subscribe to this view say that Revelation is not really teaching anything prophetical, but only spiritual principles to live by. Now this view makes the book relevant to people of all ages, and there is some degree of truth to it, because, especially during the times of great tribulation, the church receives great consolation and comfort from this book. At the end of Revelation God is triumphant and puts an end to all enmity and evil.
