I Am the True Vine: A Study of John 15:1-17

The seventh and final of the I am sayings in John's Gospel is spoken not to a crowd but to eleven men on the night before the crucifixion. Jesus has finished the meal, Judas has gone, and the discourse that began with troubled hearts in chapter 14 continues. Some readers think the words of chapter 15 were spoken on the walk from the upper room toward the Kidron valley, since chapter 14 ends with Jesus saying they should leave. Whether or not that is so, the image would have been close at hand. Vineyards covered the slopes around Jerusalem, and the temple itself was decorated with a great golden vine.

The image had a history. Israel is called a vine in Psalm 80, brought out of Egypt and planted in the land. Isaiah 5 sings of a vineyard that God planted and tended, which yielded only bad fruit. Jeremiah and Ezekiel take up the same picture, and the point in each case is disappointment. The vine God planted did not produce what he was looking for. When Jesus says he is the true vine, he is claiming to be what Israel was meant to be. The fruit the Father has waited for will come, at last, through him.

The Father is the gardener. This is a working image, not a decorative one. A vine grower does two things that look similar and are not. He removes branches that bear nothing, and he cuts back branches that bear something so that they will bear more. Both involve the knife. The Greek words for cut off and prune sound alike, and the wordplay continues when Jesus tells the disciples that they are already clean, or pruned, because of the word he has spoken to them. They have been prepared. What remains is for them to stay.

That word, remain, is the hinge of the passage. It appears again and again in these seventeen verses. Remain in me. Remain in my love. If you remain in me and my words remain in you. Some translations use abide. Either way, the idea is of staying put, dwelling, continuing in a relationship rather than drifting from it. A branch does not do anything to receive sap except stay attached. Jesus is telling the disciples that their entire fruitfulness depends on a connection they must not sever.

What does remaining look like in practice? The passage answers directly. It looks like Jesus' words remaining in them, so that his teaching shapes their thinking and praying. It looks like keeping his commands, which he says is exactly how he remains in the Father's love. It looks like asking, since those who remain may ask whatever they wish and it will be done for them, a promise that only makes sense for people whose desires have been formed by the vine. And it looks like love for one another, which is the command he singles out.

The fruit is not defined in one word, but the context suggests what it is. It is the character and conduct that come from Jesus' life flowing through a person, chiefly love, and along with it joy, obedience, and prayer that is answered. Elsewhere Paul lists the fruit of the Spirit, and that list reads like a portrait of Jesus. Fruit, in other words, is Christlikeness, and it brings glory to the Father because it shows what he is like and proves that the disciples belong to his Son.

Verse 6 is the hard verse, and honest study cannot go around it. Jesus says that if anyone does not remain in him, he is like a branch that is thrown away and withers, and such branches are gathered, thrown into the fire, and burned. Christians have read this in different ways. Some see the fruitless branch as a person who was never truly joined to Christ, a Judas figure, outwardly attached but inwardly dead. Others see a warning that real believers should take with full seriousness. Whichever reading one holds, the pastoral force is the same. Attachment to Jesus is not something to presume upon. It is to be practiced. The safe place is not in having once been near the vine but in remaining in it now.

From verse 9, the image gives way to plain speech, and the theme becomes love. The Father has loved the Son. The Son has loved the disciples with that same love. The disciples are to remain in it by keeping his commands, as he kept the Father's. Then comes a sentence that many overlook. Jesus has told them these things so that his joy may be in them and their joy may be complete. Obedience, in Jesus' view, is not the tax paid on joy. It is the place where joy lives. A branch that stays in the vine is not deprived. It is fed.

His command is that they love each other as he has loved them, and he immediately defines the measure. Greater love has no one than this, to lay down one's life for one's friends. Within twenty-four hours he will do exactly that. Then he changes their status. He no longer calls them servants, because a servant does not know his master's business. He calls them friends, because he has made known to them everything he learned from the Father. Friendship with Jesus rests on his openness, not on their achievement.

Finally, in verse 16, he addresses the question of who chose whom. They did not choose him. He chose them and appointed them to go and bear fruit that will last, so that the Father will give them whatever they ask in his name. The word appointed suggests being set in place, like a branch grafted where the gardener wants it. The disciples are not volunteers who signed up. They are chosen and positioned, and their fruit is meant to endure. Then the command is repeated one last time. Love each other.

Reading the passage as a whole, several things stand out. First, Christian life is organic before it is organizational. It is about a living connection to a living Lord, and everything else grows from that. Second, the Father's hand on the knife is a hand of care, and loss for a believer is never merely loss. Third, remaining is active, and its shape is obedience, prayer, and love. Fourth, joy is found inside obedience, not outside it. And fifth, the whole thing rests on Jesus' choice of us and not ours of him, which is the only ground stable enough to hold a life.

As you close this study, consider a few questions. Which of the practices of remaining, his words in you, keeping his commands, asking in prayer, loving one another, has grown thin in your life, and what would restoring it look like this week? Where are you experiencing the gardener's knife right now, and can you name what he may be clearing space for? And if you took seriously that Jesus calls you a friend and has told you his Father's business, how would that change the way you pray tonight?
