John 14:26

But the Comforter, which is the Holy Ghost. — Better, as before, but the Advocate... (Comp. Excursus G: The Meaning of the word Paraclete.) For the words “Holy Ghost” comp. John 7:39; John 20:22, which are the only passages where we find them in this Gospel. They are frequent in the earlier Gospels. (See Note on Matthew 12:31.) In four passages in the New Testament (Luke 11:13; Ephesians 1:13; Ephesians 4:30; 1 Thessalonians 4:8) our translators have preferred the rendering “Holy Spirit.” The identification here with the Advocate brings out the contrast between the practical obedience and holiness (John 14:23) of those to whom the Holy Spirit should be sent, and the disobedience (John 14:24) of those who rejected the revelation by the Son.

Whom the Father will send in my name — i.e., as My representative. (Comp. John 14:13.) Their Master will depart from them, but the Father will send them another Teacher who will make clear to them the lessons they have already heard, and teach them things which they cannot bear now.

He shall teach you all things. — Comp. John 16:13. The words are here without an expressed limitation, but the “all things” here is equal to the “all truth” in the later passage.

And bring all things to your remembrance, whatsoever I have said unto you. — The limitation, “whatsoever I have said unto you,” is to be taken with this clause only, and is not to be extended to the words, “He shall teach you all things.” For instances of the recurrence of words spoken by our Lord with a fulness of new meaning revealed in them by the Holy Spirit, comp. John 2:22; John 12:16. The Gospel according to St. John, with its full records of the words spoken by our Lord, is itself a commentary on this text.
