Then, still further, there is a twofold description here of the mission of this divine Champion, as 'sent' by Christ, and 'proceeding from the Father.'
In regard to the former, I need only remind you that, in a previous part of this wonderful discourse, our Lord speaks of that divine Spirit as being sent by the Father in His name and in answer to His prayer. The representation here is by no means antagonistic to, or diverse from, that other representation, but rather the fact that the Father and the Son, according to the deep teaching of Scripture, are in so far one as that 'whatsoever the Son seeth the Father do that also the Son doeth likewise,' makes it possible to attribute to Him the work which, in another place, is ascribed to the Father. In speaking of the _Persons_ of the Deity, let us never forget that that word is only partially applicable to that ineffable Being, and that whilst with us it implies absolute separation of individuals, it does not mean such separation in the case of its imperfect transference to the mysteries of the divine nature; but rather, the Son doeth what the Father doeth, and therefore the Spirit is sent forth by the Father, and also the Son sends the Spirit.
But, on the other hand, we are not to regard that divine Spirit as merely a Messenger sent by another. He 'proceeds from the Father.' That word has been the battlefield of theological controversy, with which I do not purpose to trouble you now. For I do not suppose that in its use here it refers at all to the subject to which it has been sometimes applied, nor contains any kind of revelation of the eternal depths of the divine Nature and its relations to itself. What is meant here is the historical coming forth into human life of that divine Spirit. And, possibly, the word 'proceeds' is chosen in order to contrast with the word 'sent,' and to give the idea of a voluntary and personal action of the Messenger, who not only is _sent_ by the Father, but of Himself _proceeds_ on the mighty work to which He is destined.
Be that as it may, mark only, for the last thought here about the details of this great promise, that wonderful phrase, twice repeated in our Lord's words, and emphasised by its verbal repetition in the two clauses, which in all other respects are so different--'from the Father.' The word translated '_from_' is not the ordinary word so rendered, but rather designates _a position at the side of_ than an _origin from_, and suggests much rather the intimate and ineffable union between Father, Son, and Spirit, than the source from which the Spirit comes. I touch upon these things very lightly, and gather them up into one sentence. Here, then, are the points. A Person who is spoken of as 'He'--a divine Person whose home from of old has been close by the Father's side--a Person whose instrument is the revealed truth ensphered and in germ in the facts of Christ's incarnation and life--a divine Person, wielding the truth, who is sent by Christ as His Representative, and in some sense a continuance of His personal Presence--a divine, personal Spirit coming from the Father, wielding the truth, sent by Christ, and at the side of all the persecuted and the weak, all world-hated and Christian men, as their Champion, their Combatant, their Ally, their Inspiration, and their Power. Is not that enough to make the weakest strong? Is not that enough to make us 'more than conquerors through Him that loved us'? All nations have legends of the gods fighting at the head of their armies, and through the dust of battle the white horses and the shining armour of the celestial champions have been seen. The childish dream is a historical reality. It is not we that fight, it is the Spirit of God that fighteth in us.
