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.
Having dealt with the eternal state of the wicked, we now come to consider the eternal, everlasting bliss which lies ahead for the righteous. The Great Judge will say to the unbelievers, “Depart from me, ye cursed.” But he says to those who trust in him, “Come, ye blessed of my Father, inherit the kingdom prepared for you from the foundation of the world”—Matthew 25, verse 34. How awful is that word “depart”—depart forever. But how wonderful is that word “come”—come and dwell with me forever. Jesus had comforted his disciples as he was about to leave them the night before he was crucified.
