'If I go not away the Comforter will not come unto you, but if I depart I will send Him unto you.' Now we have already, in former sermons, touched upon many of the themes which would naturally be suggested by these words, and therefore I do not propose to dwell upon them at any length. There is only one point to which I desire to refer briefly here, and that is the necessity which here seems to be laid down by our Lord for His departure, in order that that divine Spirit may come and dwell with men. That necessity goes down deeper into the mysteries of the divinity and of the processes and order of divine revelation than it is given to us to follow. But though we can only speak superficially and fragmentarily about such a matter, let me just remind you, in the briefest possible words, of what Scripture plainly declares to us with regard to this high and, in its fullness, ineffable matter. It tells us that the complete work of Jesus Christ--not merely His coming upon earth, or His life amongst men, but also His sacrificial death upon the Cross--was the necessary preliminary, and in some sense procuring cause, of the gift of that divine Spirit. It tells us--and there we are upon ground on which we can more fully verify the statement--that His work must be completed ere that Spirit can be sent, because the word is the Spirit's weapon for the world, and the revelation of God in Jesus must be ended, ere the application of that revelation, which is the Spirit's work, can be begun in its full energy. It tells us, further, (and there our eyesight fails, and we have to accept what we are told), that Jesus Christ must ascend on high and be at the right hand of God, ere He can pour down upon men the fullness of the Spirit which dwelt uncommunicated in Him in the time of His earthly humiliation. 'Thou hast ascended up on high,' and therefore 'Thou hast given gifts to men.' We accept the declaration, not knowing all the deep necessity in the divine Nature on which it rests, but believing it, because He in whom we have confidence has declared it to us. And we are further told--and there our experience may, in some degree, verify the statement,--that only those, in whose hearts there is union to Jesus Christ by faith in His completed work and ascended glory, are capable of receiving that divine gift. So every way, both as regards the depths of Deity and the processes of revelation, and as regards the power of the humanity of Christ to impart His Spirit, and as regards the capacity of us poor recipients to receive it, the words of my text seem to be confirmed, and we can, though not with full insight, at any rate with full faith, accept the statement, 'If I go not away, the Comforter will not come to you.' That coming is gain. It teaches a deeper knowledge of Him. It teaches and gives a fuller possession of the life of righteousness which is like His own. It draws us into the fellowship of the Son.
