14:25-31 "I have spoken these things to you while to you while I am still with you. The Helper, the Holy Spirit, whom the Father will send in my name, will teach you all things, and will remind you of all that I have said. I am leaving you peace: I am giving you my peace. I do not give it to you as the world gives peace. Let not your heart be distressed or fear-stricken. You have heard that I said to you: 'I am going away and I am coming to you.' If you loved me, you would be glad that I am going to my Father, because the Father is greater than I. And now I have told you about it before it happens, so that whenever it does happen, you will believe. I shall not say much more to you, because the prince of this world is coming. He has no hold over me. His coming will only make the world know that I love the Father, and that I do as the Father has commanded me. Rise, let us be going."
This a passage close-packed with truth. In it Jesus speaks of five things.
(i) He speaks of his ally, the Holy Spirit, and says two basic things about him.
(a) The Holy Spirit will teach us all things. To the end of the day the Christian must be a learner, for to the end of the day the Holy Spirit will be leading him deeper and deeper into the truth of God. There is never any excuse in the Christian faith for the shut mind. The Christian who feels that he has nothing more to learn is the Christian who has not even begun to understand what the doctrine of the Holy Spirit means.
(b) The Holy Spirit will remind us of what Jesus has said. This means two things. 1. In matters of belief, the Holy Spirit is constantly bringing back to us the things Jesus said. We have an obligation to think, but all our conclusions must be tested against the words of Jesus. It is not so much the truth that we have to discover; he told us the truth. What we have to discover is the meaning of that truth. The Holy Spirit saves us from arrogance and error of thought. 2. The Holy Spirit will keep us right in matters of conduct. Nearly all of us have this sort of experience in life. We are tempted to do something wrong and are on the very brink of doing it, when back into our mind comes a saying of Jesus, the verse of a psalm, the picture of Jesus, words of someone we love and admire, teaching we received when very young. In the moment of danger these things flash unbidden into our minds. That is the work of the Holy Spirit.
(ii) He speaks of his gift, and his gift is peace. In the Bible the word for peace, shalowm ( Hebrew #7965 ), never means simply the absence of trouble. It means everything which makes for our highest good. The peace which the world offers us is the peace of escape, the peace which comes from the avoidance of trouble and from refusing to face things. The peace which Jesus offers us is the peace of conquest. No experience of life can ever take it from us and no sorrow, no danger, no suffering can ever make it less. It is independent of outward circumstances.
(iii) He speaks of his destination. He is going back to his Father; and he says that if his disciples really loved him, they would be glad that it was so. He was being released from the limitations of this world; he was being restored to his glory. If we really grasped the truth of the Christian faith, we would always be glad when those whom we love go to be with God. That is not to say that we would not feel the sting of sorrow and the sharpness of loss; but even in our sorrow and our loneliness, we would be glad that after the troubles and the trials of earth those whom we loved have gone to something better. We would never grudge them their rest but would remember that they had entered, not into death, but into blessedness.
(iv) He speaks of his struggle. The Cross was the final battle of Jesus with the powers of evil. But he was not afraid of it, for he knew that evil had no ultimate power over him. He went to his death in the certainty, not of defeat, but of conquest.
(v) He speaks of his vindication. At the moment men saw in the Cross only his humiliation and his shame; but the time would come when they would see in it his obedience to God and his love to men. The very things which were the keynotes of Jesus' life found their highest expression in the Cross.
