These things I have spoken to you. He again states that none of those things which he has spoken are superfluous; for, since wars and contests await them, it is necessary that they should be provided beforehand with the necessary arms. Yet he also means that, if they meditate deeply on this doctrine, they will be fully prepared for resistance. Let us remember that what he then said to the disciples is also spoken to us. And, first, we ought to understand that Christ does not send his followers into the field unarmed, and, therefore, that, if any man fail in this warfare, his own indolence alone is to blame. And yet we ought not to wait till the struggle be actually commenced, but ought rather to endeavor to become well acquainted with these discourses of Christ, and to render them familiar to our minds, so that we may march into the field of battle, as soon as it is necessary; for we must not doubt that the victory is in our hands, so long as those admonitions of Christ shall be deeply imprinted on our minds. For, when he says THAT YOU MAY NOT be offended, he means that there is no danger, lest anything turn us aside from the right course. But how few there are that learn this doctrine in a proper manner, is evident from this fact, that they who think that they know it by heart when they are beyond arrow-shot, are no sooner obliged to enter into actual combat than they give way, as if they were utterly ignorant, and had never received any instruction. [1] Let us, therefore accustom ourselves to use this armor in such a manner that it may never drop out of our hands.

Footnotes

1 - "Et que jamais ils n'en eussent ouy parler."

These things - The things spoken in the two previous chapters, promising them divine aid and directing them in the path of duty.
Be offended - For the meaning of the word offend, see the notes at Matthew 5:29. It means here the same as to stumble or fall - that is, to apostatize. He proceeds immediately to tell them, what he had often apprised them of, that they would be subject to great persecutions and trials. He was also himself about to be removed by death. They were to go into an unfriendly world. All these things were in themselves greatly fitted to shake their faith, and to expose them to the danger of apostasy. Compare Luke 24:21. If they had not been apprised of this, if they had not known why Jesus was about to die, and if they had not been encouraged with the promised aid of the Holy Spirit, they would have sunk under these trials, and forsaken him and his cause. And we may learn hence:
1. that if Christians were left to themselves they would fall away and perish.
2. that God affords means and helps beforehand to keep them in the path of duty.
3. that the instructions of the Bible and the help of the Holy Spirit are all granted to keep them from apostasy.
4. that Jesus beforehand secured the fidelity and made certain the continuance in faith of his apostles, seeing all their dangers and knowing all their enemies. And, in like manner, we should be persuaded that "he is able to keep that which we commit to him against that day," 2-Timothy 1:12.

These things have I spoken - Particularly what is mentioned in the two last chapters.
Be offended - Ἱνα μη σκανδαλισθητε, That ye should not be stumbled. May not fall away from the faith, nor receive any injury to your souls, as that man does to his body who stumbles, or falls over a stone, or block, in the way which he has not discovered.

These (1) things have I spoken unto you, that ye should not be offended.
(1) The ministers of the gospel must expect all types of reproaches, not only by those who are open enemies, but even by those also who seem to be of the same household, and the very pillars of the Church.

These things have I spoken unto you,.... Concerning the world's hatred and persecution of them, and the little regard they would show to their doctrine: these things Christ thought, proper to give them notice of before hand, that expecting them, they might be prepared for them, and be fortified against them;
that, says he,
ye should not be offended: his view in speaking of them, was not to discourage them, but to prevent their stumbling at them, and falling by them. Hardships coming upon persons at unawares, bear the harder upon their spirits, and they are more apt to take offence at them and be impatient under them, which is prevented by previous intimation: had Christ said nothing of these things that should befall his disciples, they might have surprised them, and have been a stumbling to them; and might have tempted them to have relinquished their profession of him, and dropped their ministerial work; whereas being apprized of them before hand, they were not so shocking to them. This shows the tender concern of Christ for his disciples, how careful he was to remove, every occasion of stumbling, or what might be matter of offence to them; and may teach us to act in such like manner towards one another, in this, or any other case.

Our Lord Jesus, by giving his disciples notice of trouble, designed that the terror might not be a surprise to them. It is possible for those who are real enemies to God's service, to pretend zeal for it. This does not lessen the sin of the persecutors; villanies will never be changed by putting the name of God to them. As Jesus in his sufferings, so his followers in theirs, should look to the fulfilling of Scripture. He did not tell them sooner, because he was with them to teach, guide, and comfort them; they needed not then this promise of the Holy Spirit's presence. It will silence us to ask, Whence troubles come? It will satisfy us to ask, Whither go they? for we know they work for good. It is the common fault and folly of melancholy Christians to look only on the dark side of the cloud, and to turn a deaf ear to the voice of joy and gladness. That which filled the disciples' hearts with sorrow, was too great affection for this present life. Nothing more hinders our joy in God, than the love of the world, and the sorrow of the world which comes from it.

DISCOURSE AT THE SUPPER TABLE CONCLUDED. (John 16:1-33)
These things have I spoken unto you, that ye should not be offended--both the warnings and the encouragements just given.

These things have I spoken. The warnings found in the 14th and 15th chapters. They were given beforehand lest they should stumble. To be forewarned would be a help to their faith amid the dark scenes of the next few days, and in the persecutions that would come later.
