John 16:13

He will guide you - He will consider your feeble infant state; and, as a father leads his child by the hand, so will the Holy Spirit lead and guide you.

The Vulgate, and some copies of the Itala, read, He will Teach you all truth; but this and more is implied in the word ὁδηγησει, he will lead; besides, this reading is not acknowledged by any Greek MS.

He shall not speak of himself - He shall teach nothing contrary to what I have taught you:

But whatsoever he shall hear - Of the Father and me, that he shall speak, and thus show the intimate consent between himself, the Father, and Christ. It is one conjoint testimony, in which the honor and glory of the holy Trinity, and man's salvation are equally concerned.

And he will show you things to came - He will fully explain every thing that may now appear dark or difficult to you; will give you such a knowledge of futurity as shall, in all necessary cases, enable you to foretell future events; and shall supply every requisite truth, in order to make the new covenant revelation complete and perfect.

The Spirit of truth - So called because he would teach them all necessary truth.

Will guide you into all truth - That is, truth which pertained to the establishment of the Christian system, which they were not then prepared to hear. We may here remark that this is a full promise that they would be inspired and guided in founding the new church; and we may observe that the plan of the Saviour was replete with wisdom. Though they had been long with him, yet they were not prepared then to hear of the changes that were to occur; but his death would open their eyes, and the Holy Spirit, making use of the striking and impressive scenes of his death and ascension, would carry forward with vast rapidity their views of the nature of the Christian scheme. Perhaps in the few days that elapsed, of which we have a record in the first and second chapters of the Acts of the Apostles, they learned more of the true nature of the Christian plan than they would have done in months or years even under the teaching of Jesus himself. The more we study the plan of Christ, the more shall we admire the profound wisdom of the Christian scheme, and see that it was eminently fitted to the great design of its Founder - to introduce it in such a manner as to make on man the deepest impression of its wisdom and its truth.

Not speak of himself - Not as prompted by himself. He shall declare what is communicated to him. See the notes at John 7:18.

Whatsoever he shall hear - What he shall receive of the Father and the Son; represented by hearing, because in this way instruction is commonly received. See the notes at John 5:30.

Things to come - Probably this means the meaning of things which were to take place after the time when he was speaking to them - to wit, the design of his death, and the nature of the changes which were to take place in the Jewish nation. It is also true that the apostles were inspired by the Holy Spirit to predict future events which would take place in the church and the world. See Acts 11:28; Acts 20:29; Acts 21:11; 1 Timothy 4:1-3; 2 Timothy 3; 2 Peter 1:14; and the whole book of Revelation.

16:13 When he is come - It is universally allowed that the Father, Son, and Holy Ghost dwell in all believers. And the internal agency of the Holy Ghost is generally admitted. That of the Father and the Son, as represented in this Gospel, deserves our deepest consideration.
