When you think about it, prophecy is just history. The only difference is, in Bible prophecy some of the history hasn’t happened yet. 

This brings us to another important key: “Images in prophecy have an on-going nature.” This is because God sees the end from the beginning at the same time. For example, we find a great, red, seven-headed dragon mentioned in the book of Revelation, the last book of the Bible. This dragon represents the way God sees Satan and the subjects he controls. In Genesis, the first book of the Bible, Satan is described as a serpent. Between the time of his first encounter with humankind in Eden, to his final defeat at the return of Christ, Satan will have grown into a great red dragon with seven heads.

So, keep in mind that the images in prophecy have an on-going nature.
