II. And so note, secondly, the witness of the Spirit which fortifies against the world.
'He shall bear witness of Me.' Now we must especially observe here that little phrase, 'unto you.' For that tells us at once that the witness which our Lord has in mind here is something which is done within the circle of the Christian believers, and not in the wide field of the world's history or in nature. Of course it is a great truth that long before Jesus Christ, and to-day far beyond the limits of His name and knowledge, to say nothing of His faith and obedience, the Spirit of God is working. As of old He brooded over the chaotic darkness, ever labouring to turn chaos into order, and darkness into light, and deformity into beauty; so today, all over the field of humanity, He is operating. Grand as that truth is, it is not the truth here. What is spoken of here is something that is done in and on Christian men, and not even through them on the world, but in them for themselves. 'He shall testify of Me' to you.
Now it is to be noted, also, that the first and special application of these words is to the little group listening to Him. Never were men more desolate and beaten down than these were, in the prospect of Christ's departure. Never were men more utterly bewildered and dispirited than these were, in the days between His crucifixion and His resurrection. Think of them during His earthly life, their narrow understandings, their manifold faults, moral as well as intellectual. How little perception they had of anything that He said to them, as their own foolish questions abundantly show! How little they had drunk in His spirit, as their selfish and ambitious janglings amongst themselves abundantly show! They were but Jews like their brethren, believing, indeed, that Jesus Christ was the Messiah, but not knowing what it was that they believed, or of what kind the Messiah was in whom they were thus partially trusting. But they loved Him and were led by Him, and so they were brought into a larger place by the Spirit whom Christ sent.
What was it that made these dwarfs into giants in six weeks? What was it that turned their narrowness into breadth; that made them start up all at once as heroes, and that so swiftly matured them, as the fruits and flowers are ripened under tropical sunshine? The resurrection and ascension of Jesus Christ had a great deal to do with the change; but they were not its whole cause. There is no explanation of the extraordinary transformation of these men as we see them in the pages of the Gospels, and as we find them on the pages of the Acts of the Apostles, except this--the resurrection and the ascension of Jesus Christ as facts, and the Spirit on Pentecost as an indwelling Interpreter of the facts. He came, and the weak became strong, and the foolish wise, and the blind enlightened, and they began to understand--though it needed all their lives to perfect the teaching,--what it was that their ignorant hands had grasped and their dim perceptions had seen, when they touched the hands and looked upon the face of Jesus Christ. The witness of the Spirit of God working within them, working upon what they knew of the historical facts of Christ's life, and interpreting these to them, was the explanation of their change and growth. And the New Testament is the product of that change. Christ's life was the truth which the Spirit used, and a product of His teaching was these Epistles which we have, and which for us step into the place which the historical facts held for them, and become the instrument with which the Spirit of God will deepen our understanding of Christ and enlarge our knowledge of what He is to us.
