Eschatology
Eschatology is the science or study of the ultimate destiny or purpose of mankind and the world. Over one fourth of the books of the Bible are declared to be primarily prophetic. At least one fifth of the actual text of the Bible was a prediction at the time it was given. Very few Biblical prophecies have been fully understood until after the fulfillment of that prophecy. Even today, we do not need to know the meaning of all aspects of the prophecy, nor should we try to fill in the blanks where the prophecies do not give all the detail. It is the task of the teacher of prophecy is to present what is stated in one passage compared with all other prophecies. They are to teach what is clearly spoken in Scripture.
