Jn. 15:20. Remember the word that I said to you: A servant is not greater than his master. If they persecuted Me, they will also persecute you; if they kept My word, they will keep yours also.
What He said above, namely, that they hated Me before they hated you, He now sets forth more extensively, offering them greater consolation. "Remember," He says, "My word that a servant is not greater than his master. And you are not greater than Me. See then how they treated Me. If they persecuted Me—the Master, all the more will they persecute you—the servants. If they did not persecute Me but kept My word, then they will keep yours as well."
Jn. 15:21. But all these things they will do to you for My name's sake,
But this is not so. They will keep neither My word nor yours. But all that they will do to you on account of Me. Therefore, if you love Me, endure what you suffer for My sake, Whom, by your own words, you love.
Jn. 15:21. "because they do not know Him who sent Me."
Here is yet another reason for consolation. They, by wronging you, insult at the same time also Him Who sent Me. Therefore, if nothing else, then this very fact—that the same people are enemies to you and to Me and to My Father—should serve as your consolation.
Jn. 15:22. If I had not come and spoken to them, they would not have sin; but now they have no excuse for their sin.
Is it really just that they do this? They hate both Me and My Father and you? Did they really find in My words or deeds a reason for such behavior? No, their sin is unforgivable. For did I not come and teach? If I had not come, if I had not spoken, they could have said "we did not hear." But now their malice is inexcusable.
Jn. 15:23. He who hates Me hates My Father also.
Then, since they everywhere appealed to nothing other than the claim that they were defending the Father (for they say: "This man is not from God," and the like (John 9:16)), He therefore adds: "He who hates Me hates My Father also." Thus, even this serves in no way to justify them.
Jn. 15:24. If I had not done among them the works which no one else did, they would have no sin; but now they have both seen and hated both Me and My Father.
I did not merely deliver teaching, but also performed works such as no one else had done—for example, the miracle with the blind man, with Lazarus, and other similar ones. What justification, then, do they have? For My part, I delivered teaching in words and added the proof of works. And Moses (Deut. 18:18–22) commands to heed the one who performs miracles and teaches piety. But they have now both seen such works and yet hated both Me and My Father.
Jn. 15:25. But that the word written in their law might be fulfilled: They hated Me without cause.
Then He refers to the testimony of the prophet: "They hated Me without a cause" (Ps. 68:5). Their hatred was born from malice alone, and from no other reason. By "Law," as we have often said, He means not only the Law of Moses, but also the Books of the Prophets, as here He called the Book of David "Law." David, by the Holy Spirit, foretold what their malice would do; and they, without doubt, out of malice fulfilled what the prophet had predicted, and thereby confirmed the truth of the prophecy.
Jn. 15:26. When the Comforter comes,
The Lord said to the disciples: "You will be persecuted, your word will not be kept." They could have said: "Lord, why then are You sending us? How will they believe us? Who will heed us? Who will listen to us?" Lest they say this, the Lord adds: "When the Comforter comes, He will testify of Me." He is a trustworthy witness. Therefore, those convicted by the Spirit that they sin without excuse will accept your preaching.
Jn. 15:26. Which I will send to you from the Father,
The words "Whom I will send" show His equality with the Father. For in another place He said that the Father will send the Spirit (John 14:26), but here He says that He Himself will send Him. By this He shows nothing other than equality. And lest they think that He rises up against the Father when He sends the Spirit by a different authority, He added "from the Father." I will send Him Myself, but "from the Father," that is, by the good pleasure of the Father, and I will send Him together with Him. For I do not bring forth the Spirit from My own bosom, but from the Father He is bestowed through Me.
Jn. 15:26. The Spirit of truth, Who proceeds from the Father, He will bear witness concerning Me;
When you hear "proceeds," do not understand by procession a sending forth, as the ministering spirits are sent forth; rather, procession is the natural mode of being of the Spirit. If we were to understand procession not in this way, but as an external sending forth, it would not be clear which Spirit He is speaking of. For countless are the spirits "sent forth to minister for those who will inherit salvation" (Heb. 1:14). But here, procession is a certain particular and distinctive property belonging properly to the one Spirit alone. Therefore, by procession we must understand not a sending forth, but the natural mode of being from the Father.
Jn. 15:27. And you also will bear witness, because you have been with Me from the beginning.
And you who have been with Me from the beginning will also bear witness, that both by words and by deeds I have left them without excuse. Therefore, do not be troubled. The preaching will not be without testimony; but the Spirit will bear witness through signs and wonders, and His testimony will be trustworthy. For He is the Spirit of truth. As the Spirit of truth, He will bear witness to the truth. As proceeding from the Father, He knows all things precisely, for He is from the One from Whom all knowledge comes.
This same Spirit will bear witness concerning the preaching. And you also will bear witness, because you did not hear from others, but you yourselves have been with Me from the very beginning. And the testimony of those who were with Him from the beginning is no small matter. The apostles themselves later said before the people: "Witnesses of His resurrection are we, who ate and drank with Him" (Acts 10:41).
So the testimony is from two sides: both from you and from the Spirit. Concerning you, people might think that you testify to please Me; but the Spirit will in no way testify out of flattery.
