Eschatology is the doctrine of the Last Things. It looks unto the future, and on the basis of the teaching of Scripture, sets out what will happen in the future. Some people allow their imagination to lead them into fantastical speculation. But theology should always be sober and restrained, and based upon what God has clearly revealed. In trying to interpret prophecy, we must exercise a measure of caution, as it is notoriously difficult to interpret. When Christ came the first time, he took almost everyone by surprise. Although the Jews had the wonderful and detailed prophecies of the Old Testament, and they had a clear idea in their own minds what would happen, it didn’t turn out as they expected. As one writer put it, when Christ came the first time, they all got it wrong. So it will be when Christ returns the second time. Even the best works of theology would be found to be somewhat inaccurate.
There is one matter which is very important for us to consider when thinking of the events which must occur before Christ can return. Many Christian believe that the Jews, as a people, will one day be converted to believe in Jesus as their Messiah. There is one special New Testament passage which is very important to understand when thinking of the future, and that is, Romans, chapter 11. We believe that God there makes great promises concerning the Jews, which are yet to be fulfilled.
