What, then, is the Holy Spirit, and what is it He does for us? “I will pray the Father,” Christ said, “and He shall give you another Comforter,” or “another Paraclete.” The word translated “Comforter,” which occurs so often in this discourse of our Lord, is found nowhere else in the New Testament except in the First Epistle of St. John, where it is rendered “Advocate”; “If any man sin, we have an Advocate with the Father, Jesus Christ, the righteous.” And this, without doubt, is a more faithful rendering of the word which Christ used than the more familiar “Comforter.” An advocate is one who is called to our side to be our friend and helper, more especially to plead our cause in a court of justice; and this also is the meaning of the word “Paraclete.” Perhaps, however, the word “Comforter” may be retained without loss, if only we remember to give it its full and original meaning. To “comfort” is not primarily and originally to console, but to strengthen, to fortify; and the “Comforter” whom Christ promised to His disciples was not only one who should soothe them in their sorrows, but should stand by them in all their conflicts, their unfailing friend and helper.
Further, Christ said God “shall give you another Comforter.” That is to say, Christ Himself was a Comforter, and all that He had been to His disciples the Holy Spirit should be also. And, if we examine the three chapters of this Gospel which contain this great discourse of our Lord, we shall find this idea taken up, and repeated, and developed in passage after passage. The Holy Spirit was to come in Christ’s name, as Christ’s representative and interpreter. “He shall not speak from Himself,” Christ said; “He shall bear witness of Me. He shall glorify Me; for He shall take of Mine, and shall declare it unto you.” In the presence of the Spirit Christ Himself would be present: “I will not leave you desolate,” He said; “I come unto you;” “I will see you again, and your heart shall rejoice.” And, for the sake of such a presence, a presence which was to be not for a little while but for ever, it was best for His friends that He should leave them.[25]
