There are certain other great truths within this passage.
(i) It tells us of the honesty of Jesus. "If it were not so," asked Jesus, "would I have told you that I am going to prepare a place for you?" No one could ever claim that he had been inveigled into Christianity by specious promises or under false pretenses. Jesus told men bluntly that the Christian must bid farewell to comfort ( Luke 9:57-58 ). He told them of the persecution, the hatred, the penalties they would have to bear ( Matthew 10:16-22 ). He told them of the cross which they must carry ( Matthew 16:24 ), even although he told them also of the glory of the ending of the Christian way. He frankly and honestly told men what they might expect both of glory and of pain if they followed him. He was not a leader who tried to bribe men with promises of an easy way; he tried to challenge them into greatness.
(ii) It tells us of the function of Jesus. He said, "I am going to prepare a place for you." One of the great thoughts of the New Testament is that Jesus goes on in front for us to follow. He opens up a way so that we may follow in his steps. One of the great words which is used to describe Jesus is the word prodromos ( Greek #4274 ) ( Hebrews 6:20 ). The King James Version and the Revised Standard translate it forerunner. There are two uses of this word which light up the picture within it. In the Roman army the prodromoi ( Greek #4274 ) were the reconnaissance troops. They went ahead of the main body of the army to blaze the trail and to ensure that it was safe for the rest of the troops to follow. The harbour of Alexandria was very difficult to approach. When the great corn ships came into it a little pilot boat was sent out to guide them along the channel into safe waters. That pilot boat was called the prodromos ( Greek #4274 ). It went first to make it safe for others to follow. That is what Jesus did. He blazed the way to heaven and to God that we might follow in his steps.
(iii) It tells us of the ultimate triumph of Jesus. He said: "I am coming again." The Second Coming of Jesus is a doctrine which has to a large extent dropped out of Christian thinking and preaching. The curious thing about it is that Christians seem either entirely to disregard it or to think of nothing else. It is true that we cannot tell when it will happen or what will happen, but one thing is certain--history is going somewhere. Without a climax it would be necessarily incomplete. History must have a consummation, and that consummation will be the triumph of Jesus Christ; and he promises that in the day of his triumph he will welcome his friends.
(iv) Jesus said: "Where I am, there you will also be." Here is a great truth put in the simplest way; for the Christian, heaven is where Jesus is. We do not need to speculate on what heaven will be like. It is enough to know that we will be for ever with him. When we love someone with our whole heart, we are really alive only when we are with that person. It is so with Christ. In this world our contact with him is shadowy, for we can see only through a glass darkly, and spasmodic, for we are poor creatures and cannot live always on the heights. But the best definition is to say that heaven is that state where we will always be with Jesus.
