The Third is the Idealist view, which came about under 19th century liberalism. This view maintains that the prophecies of the Apocalypse are not specific events or indicate any specific historical or future happening. Rather, they are only poetry and symbolisms.
This view ascertains principles and ideas of our war with Satan, and will repeat in various forms until the Second Coming. Its only value is teaching us that good will eventually have victory over evil. The problem is that those who hold this view refuse to associate the images with any specific future events, and miss the point that Revelation is written in an apocalyptic genre, and thus the language is clear, that the images and themes have or will have history and significance (Rev. 4:1).
The fact is that Revelation does teach us how Satan operates and we can use these principles for understanding and combating Spiritual Warfare. In addition, these principles have been in play and at work all through church history. However, this view ignores the veracity of prophecy.
