So I think if you take these plain teachings of this symbol you learn something of the operations of that Divine Spirit to which our Lord pointed in the great words of my text.
II. And now I have a second thought to suggest--viz., what Christ had to do before His longing could be satisfied.
He longed, but the longing wish was not able to bring that on which it was fixed. He had come to send this divine fire upon the earth; but there was something that stood in the way; and something needed to be done as a preliminary before the ultimate purpose of His coming could be accomplished. What that was, as I have already tried to point out, the subsequent verse tells us. I do not need, nor would it be congruous with my present purpose, to comment upon it at any length. We all know what He meant by the 'baptism,' that He had to be baptized with, and what were the dark waters into which He had to pass, and beneath which His sacred head had to be plunged. We all know that by the 'baptism' He meant His passion and His Cross. I do not dwell, either, upon the words of pathetic human shrinking with which His vision of the Cross is here accompanied, but I simply wish to signalise one thing, that in the estimation of Jesus Christ Himself it was not in His power to kindle this holy fire in humanity until He had died for men's sins. That must come first; the Cross must precede Pentecost. There can be no Divine Spirit in His full and loftiest powers poured out upon humanity until the Sacrifice has been offered on the Cross for the sins of the world. We cannot read all the deep reasons in the divine nature, and in human receptivity, which make that sequence absolutely necessary, and that preliminary indispensable. But this, at least, we know, that the Divine Spirit whom Christ gives uses as His instrument and sword the completed revelation which Christ completed in His Cross, Resurrection, and Ascension, and that, until His weapon was fashioned, He could not come.
That thought is distinctly laid down in many places in Scripture, to which I need not refer in more than a word. For instance, the Apostle John tells us that, when our Lord spoke in a cognate figure about the rivers of water which should flow from them who believed on Him, He spake of that Holy Spirit who 'was not given because that Jesus was not yet glorified.' We remember the words in the upper chamber, 'If I go not away, the Comforter will not come unto you, but if I depart I will send Him unto you.' But enough for us that He recognised the necessity, and that here His baptism of suffering comes into view, not so much for what it was itself, the sacrifice for the world's sin, as for that to which it was the necessary preliminary and introduction, the bestowment on humanity of the gift of the Divine Spirit. The old Greek legend of the Titan that stole fire from heaven tells us that he brought it to earth in a reed. Our Christ brings the heavenly fire in the fragile, hollow reed of His humanity, and the reed has to be broken in order that the fire may blaze out. 'How I wish that it were kindled! but I have a baptism to be baptized with.'
III. Lastly, what the world has to do to receive the fire.
Take these triumphant words of our Lord about what He was to do after His Cross, and contrast with them the world as it is to-day, ay! and the Church as it is to-day. What has become of the fire? Has it died down into grey ashes, choked with the cold results of its own former flaming power? Was Jesus Christ deceiving Himself? was He cherishing an illusion as to the significance and permanence of the results of His work in the world? No! There is a difference between B.C. and A.D. which can only be accounted for by the fulfilment of the promise in my text, that He did bring fire and set the world aflame. But the condition on which that fire will burn either through communities, society, humanity, or in an individual life, is trust in Him that gives it, and cleaving to Him, and the appropriate discipline. 'This spake He of the Holy Spirit which they that believe on Him should receive.'
