'These things have I spoken unto you, being yet present with you. But the Comforter, which is the Holy Ghost, whom the Father will send in My name, He shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you.'—JOHN xiv. 25, 26.
This wonderful outpouring of consolation and instruction with which our Lord sought to soothe the pain of parting is nearing its end. We have to conceive of a slight pause here, whilst He looks back upon what He has been saying and contrasts His teaching with that of the Comforter, whom He has once already, though in a different connection, promised to His followers. He speaks of His earthly residence with them as being 'an abiding,' distinctly therein referring to what He has just said, that the Father and He will, in the future, 'make their abode' with His disciples. He contrasts the outward and transitory presence which was now nearing its end, with the inward and continuous presence, which its end was to inaugurate.
And, in like manner, with, at first sight, startling humility, He contrasts 'these things,' the partial and to a large extent unintelligible utterances which He had given with His human lips, with the complete, universal teaching of that divine Spirit, who was to instruct in 'all things' pertaining to man's salvation. We have then, here, sketched in broad outline, the great truths concerning the ever-present, inward Teacher of God's Church who is to come, now that the earthly manifestation of Christ, whom the twelve called their 'Teacher,' had reached a close. I think we may best gain the deep instruction which lies in the words before us, if we look at three points of view which they bring into prominence: the Teacher, His lesson, and His scholars.
I. Now, as to the first, the promised Teacher.
I need not repeat what I have said in former sermons as to the wide sweep of that word 'the Comforter,' beyond just reminding you that it means literally one who is called to the side of another, primarily for the purpose of being his representative in some legal process; and, more widely, for any purpose of help, encouragement, and strength. That being so, 'Comforter,' in its modern sense of _Consoler_, is far too narrow for the full force of the word, which means much rather 'Comforter,' in its ancient and etymological sense of one who, in company with another, makes Him strong and brave.
But the point to which I desire to turn attention now is this, that this comforting and strengthening office of the divine Spirit is brought into immediate connection here with the conception of Him as a Teacher. That is to say, the best strength that God, by His Spirit, can give us is by our firm grasp and growing clearness of understanding of the truths which are wrapped up in Jesus Christ. All power for endurance, for service, is there, and when the Spirit of God teaches a man what God reveals in Christ, He therein and thereby most fully discharges His office of Strengthener.
Then note still further the other designation of this divine Teacher which is here given: 'The Comforter, which is the Holy Ghost.' We might have expected, as indeed we find in another context in this great final discourse, the 'Spirit of _Truth_' as appropriate in connection with the office of teaching. But is there not a profound lesson for us here in this, that, side by side with the thought of illumination, there lies the thought of purity built upon consecration, which is the Scripture definition of holiness? That suggests that there is an indissoluble connection between the real knowledge of God's truth and practical holiness of life. That connection is of a double sort. There is no holiness without such knowledge, and there is no such knowledge without holiness.
