Still in the upper room with the apostles after the memorial meal, Jesus encourages them: “Do not let your hearts be troubled. Exercise faith in God; exercise faith also in me.”​—John 13:36; 14:1.

Jesus gives the faithful apostles reason not to be troubled over his departure: “In the house of my Father are many dwelling places. . . . If I go my way and prepare a place for you, I will come again and will receive you home to myself, so that where I am you also may be.” The apostles, however, do not grasp that he is speaking about going to heaven. Thomas asks: “Lord, we do not know where you are going. How can we know the way?”​—John 14:2-5.

“I am the way and the truth and the life,” Jesus answers. Only by accepting him and his teachings and imitating his life course can one enter the heavenly house of his Father. Jesus says: “No one comes to the Father except through me.”​—John 14:6.

Philip, listening intently, requests: “Lord, show us the Father, and it is enough for us.” Philip seems to want some manifestation of God, like the visions that Moses, Elijah, and Isaiah received. However, the apostles have something better than such visions. Jesus highlights that, replying: “Even after I have been with you men for such a long time, Philip, have you not come to know me? Whoever has seen me has seen the Father also.” Jesus perfectly reflects the Father’s personality; hence, living with and observing Jesus is like seeing the Father. Of course, the Father is superior to the Son, for Jesus points out: “The things I say to you I do not speak of my own originality.” (John 14:8-10) The apostles can see that Jesus is giving all credit for his teachings to his Father.

Jesus’ apostles have seen him do wonderful works and have heard him proclaim the good news about the Kingdom of God. Now he tells them: “Whoever exercises faith in me will also do the works that I do; and he will do works greater than these.” (John 14:12) Jesus is not saying that they will perform greater miracles than he did. They will, though, carry out their ministry for a much longer time, over a much greater area, and to far more people.

Jesus’ departure will not leave them abandoned, for he promises: “If you ask anything in my name, I will do it.” Moreover, he says: “I will ask the Father and he will give you another helper to be with you forever, the spirit of the truth.” (John 14:14, 16, 17) He guarantees them that they will receive the holy spirit, this other helper. That happens on the day of Pentecost.

“In a little while,” Jesus says, “the world will see me no more, but you will see me, because I live and you will live.” (John 14:19) Not only will Jesus appear to them in bodily form after his resurrection but he will, in time, resurrect them to be with him in heaven as spirit creatures.

Now Jesus states a simple truth: “Whoever has my commandments and observes them is the one who loves me. In turn, whoever loves me will be loved by my Father, and I will love him and will clearly show myself to him.” At this the apostle Judas, who is also called Thaddaeus, asks: “Lord, what has happened that you intend to show yourself clearly to us and not to the world?” Jesus replies: “If anyone loves me, he will observe my word, and my Father will love him . . . Whoever does not love me does not observe my words.” (John 14:21-24) Unlike his followers, the world does not recognize Jesus as the way, the truth, and the life.

Jesus is going away, so how will his disciples be able to recall all that he taught them? Jesus explains: “The helper, the holy spirit, which the Father will send in my name, that one will teach you all things and bring back to your minds all the things I told you.” The apostles have seen how powerfully the holy spirit can work, so this assurance is comforting. Jesus adds: “I leave you peace; I give you my peace. . . . Do not let your hearts be troubled nor let them shrink out of fear.” (John 14:26, 27) The disciples have reason, then, not to be troubled​—they will have direction and protection from Jesus’ Father.

Evidence of God’s protection will soon be seen. Jesus says: “The ruler of the world is coming, and he has no hold on me.” (John 14:30) The Devil was able to enter into Judas and get a hold on him. But there is no sinful weakness in Jesus that Satan can play on to turn him against God. Nor will the Devil be able to restrain Jesus in death. Why not? Jesus states: “I am doing just as the Father has commanded me to do.” He is certain that his Father will resurrect him.​—John 14:31.

Jesus has been encouraging his faithful apostles in a heart-to-heart talk. It is late, perhaps past midnight. Jesus now presents a motivating illustration:

“I am the true vine, and my Father is the cultivator,” he begins. (John 15:1) His illustration resembles what had been said centuries earlier about the nation of Israel, which was called Jehovah’s vine. (Jeremiah 2:21; Hosea 10:1, 2) However, Jehovah is casting off that nation. (Matthew 23:37, 38) So Jesus is introducing a new thought. He is the vine that his Father has been cultivating since anointing Jesus with holy spirit in 29 C.E. But Jesus shows that the vine symbolizes more than just him, saying:

“[My Father] takes away every branch in me not bearing fruit, and he cleans every one bearing fruit, so that it may bear more fruit. . . . Just as the branch cannot bear fruit by itself unless it remains in the vine, neither can you unless you remain in union with me. I am the vine; you are the branches.”​—John 15:2-5.

Jesus has promised his faithful disciples that after he goes away, he would send a helper, the holy spirit. Fifty-one days later, when the apostles and others receive that spirit, they become branches of the vine. And all the “branches” would have to remain united with Jesus. To accomplish what?

He explains: “Whoever remains in union with me and I in union with him, this one bears much fruit; for apart from me you can do nothing at all.” These “branches”​—his faithful followers—​would bear much fruit, imitating Jesus’ qualities, actively speaking to others about God’s Kingdom, and making more disciples. What if one does not remain in union with Jesus and does not bear fruit? Jesus explains: “If anyone does not remain in union with me, he is thrown out.” On the other hand, Jesus says: “If you remain in union with me and my sayings remain in you, ask whatever you wish and it will take place for you.”​—John 15:5-7.

Now Jesus returns to what he has mentioned twice​—keeping his commandments. (John 14:15, 21) He describes a key way for disciples to prove that they are doing so: “If you observe my commandments, you will remain in my love, just as I have observed the commandments of the Father and remain in his love.” However, more is involved than loving Jehovah God and his Son. Jesus says: “This is my commandment, that you love one another just as I have loved you. No one has love greater than this, that someone should surrender his life in behalf of his friends. You are my friends if you do what I am commanding you.”​—John 15:10-14.

In a few hours, Jesus will demonstrate his love by giving his life for all who exercise faith in him. His example should move his followers to have similar self-sacrificing love for one another. This love will identify them, as Jesus stated earlier: “By this all will know that you are my disciples​—if you have love among yourselves.”​—John 13:35.

The apostles should take note of Jesus’ calling them “friends.” He relates why they are such: “I have called you friends, because I have made known to you all the things I have heard from my Father.” What a precious relationship to have​—to be intimate friends of Jesus and to know what the Father told him! In order to enjoy this relationship, though, they must “keep bearing fruit.” If they do, Jesus says, “no matter what you ask the Father in my name he [will] give it to you.”​—John 15:15, 16.

The love among these “branches,” his disciples, will help them to endure what is to come. He warns them that the world will hate them, yet he offers this comfort: “If the world hates you, you know that it has hated me before it hated you. If you were part of the world, the world would be fond of what is its own. Now because you are no part of the world, . . . for this reason the world hates you.”​—John 15:18, 19.

Explaining further why the world will hate them, Jesus adds: “They will do all these things against you on account of my name, because they do not know the One who sent me.” Jesus says that his miraculous works, in effect, convict those who hate him: “If I had not done among them the works that no one else did, they would have no sin; but now they have both seen me and hated me as well as my Father.” Actually, their hatred fulfills prophecy.​—John 15:21, 24, 25; Psalm 35:19; 69:4.

Again, Jesus promises to send the helper, the holy spirit. That powerful force is available for all his followers and is able to help them to bear fruit, “to bear witness.”​—John 15:27.

Jesus and the apostles are poised to leave the upper room where they held the Passover meal. Having given them considerable admonition, Jesus adds: “I have said these things to you so that you may not be stumbled.” Why was such a warning appropriate? He tells them: “Men will expel you from the synagogue. In fact, the hour is coming when everyone who kills you will think he has offered a sacred service to God.”​—John 16:1, 2.

That may be troubling news for the apostles. Although Jesus had said earlier that the world would hate them, he had not directly told them that they would be killed. Why not? “I did not tell you these things at first, because I was with you,” he says. (John 16:4) Now he is forearming them before he departs. This may help them to avoid being stumbled later.

Jesus continues: “I am going to the One who sent me; yet not one of you asks me, ‘Where are you going?’” Earlier that evening they had inquired about where he was going. (John 13:36; 14:5; 16:5) But now, shaken by what he said about persecution, they are absorbed in their own grief. Thus they fail to ask further about the glory that awaits him or what that would mean for true worshippers. Jesus observes: “Because I have told you these things, grief has filled your hearts.”​—John 16:6.

Then Jesus explains: “It is for your benefit that I am going away. For if I do not go away, the helper will not come to you; but if I do go, I will send him to you.” (John 16:7) Only by Jesus’ dying and going to heaven can his disciples receive the holy spirit, which he can send as a helper to his people anywhere on earth.

The holy spirit “will give the world convincing evidence concerning sin and concerning righteousness and concerning judgment.” (John 16:8) Yes, the world’s failure to exercise faith in God’s Son will be exposed. Jesus’ ascension to heaven will provide convincing evidence of his righteousness and will demonstrate why Satan, “the ruler of this world,” merits adverse judgment.​—John 16:11.

“I still have many things to say to you,” Jesus continues, “but you are not able to bear them now.” When he pours out the holy spirit, it will guide them to an understanding of “all the truth,” and they will be able to live by that truth.​—John 16:12, 13.

The apostles are puzzled by Jesus’ further statement: “In a little while you will see me no longer, and again, in a little while you will see me.” They ask one another what he means. Jesus realizes that they want to question him about this, so he explains: “Most truly I say to you, you will weep and wail, but the world will rejoice; you will be grieved, but your grief will be turned into joy.” (John 16:16, 20) When Jesus is killed the next afternoon, the religious leaders rejoice, but the disciples grieve. Then their grief changes into joy when Jesus is resurrected! And their joy continues when he pours out upon them God’s holy spirit.

Comparing the apostles’ situation to that of a woman during birth pangs, Jesus says: “When a woman is giving birth, she has grief because her hour has come, but when she has given birth to the child, she remembers the tribulation no more because of the joy that a man has been born into the world.” Jesus encourages his apostles, saying: “You also, now you have grief; but I will see you again, and your hearts will rejoice, and no one will take away your joy.”​—John 16:21, 22.

Up to this time, the apostles have never made requests in Jesus’ name. He now says: “In that day you will make request of the Father in my name.” Why are they to do so? Not because the Father is reluctant to respond. In fact, Jesus says: “The Father himself has affection for you, because you have had affection for me . . . as God’s representative.”​—John 16:26, 27.

Jesus’ encouraging words to the apostles may have emboldened them to affirm: “By this we believe that you came from God.” That conviction will soon be tested. In fact, Jesus describes what is just ahead: “Look! The hour is coming, indeed, it has come, when each one of you will be scattered to his own house and you will leave me alone.” Yet he assures them: “I have said these things to you so that by means of me you may have peace. In the world you will have tribulation, but take courage! I have conquered the world.” (John 16:30-33) No, Jesus is not abandoning them. He is sure that they too can be world conquerors, just as he is, by their faithfully accomplishing God’s will despite the attempts of Satan and his world to break their integrity.
