Then, still further, the other designation here of this strong Succourer and Friend is 'the Spirit of truth,' by which is designated, not so much His characteristic attribute, as rather the weapon which He wields, or the material with which He works. The 'truth' is His instrument; that is to say, the Spirit of God sent by Jesus Christ is the Strengthener, the Encourager, the Comforter, the Fighter for us and with us, because He wields that great body of truth, the perfect revelation of God, and man, and duty, and salvation, which is embodied in the incarnation and work of Jesus Christ our Lord. The truth is His weapon, and it is by it that He makes us strong. 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.
