This Is Eternal Life

Read

John 17 is unlike anything else in this gospel. The chapters before it have been conversation — Jesus speaking to his disciples. This chapter is prayer. He lifts his eyes to heaven and speaks to the Father, and John records all of it.

In the other gospels we see Jesus pray — at the tomb of Lazarus, in Gethsemane, on hillsides alone. But here, for twenty-six verses, we hear the whole content of his prayer. Read it slowly, as you would read a letter not written to you that you have been given permission to read. Then notice, near the end, the moment it becomes a letter to you directly.

Walk-through

The hour, and a definition (verses 1–5)

Jesus said these things, and lifting up his eyes to heaven, he said, "Father, the time has come. Glorify your Son, that your Son may also glorify you."

John 17:1

The hour Jesus has referred to since chapter 2 — my hour has not yet come — is now here. He does not pray to be delivered from it. He prays that what is coming will accomplish what it is meant to accomplish.

He prays that the Son may be glorified so that the Son may glorify the Father. And then he says what the Father has authorised him to give:

This is eternal life, that they should know you, the only true God, and him whom you sent, Jesus Christ.

John 17:3

This is the only place in this gospel where eternal life is defined, and the definition matters. It is not life that does not end — though it includes that. It is not a location, a reward, an outcome achieved at death. It is a relationship: knowing the only true God, and Jesus Christ whom he sent. Knowing in the deep sense the whole gospel has been building — the kind of knowing a shepherd has of his sheep, the kind the Father has of the Son. Not information about God, but acquaintance with him.

He adds: I have finished the work you gave me. Not yet — crucifixion is hours away — but from where he stands, it is already done. Restore me, he asks, to the glory I had with you before the world existed.

Keep them (verses 6–19)

He turns to pray for the people the Father gave him. He has revealed the Father's name to them. They have received his words and believed that the Father sent him. Now he is going, and they remain.

"I am no more in the world, but these are in the world, and I am coming to you. Holy Father, keep them through your name which you have given me, that they may be one, even as we are."

John 17:11

The unity he prays for — that they may be one, even as we are — is the unity of the Father and the Son. Not institutional agreement. Not uniform opinion. The kind of unity that exists between persons who are fully themselves and fully given to each other. It is a high standard, and it is what he asks for.

He says he is not asking the Father to take them out of the world:

"I pray not that you would take them from the world, but that you would keep them from the evil one. They are not of the world even as I am not of the world. Sanctify them in your truth. Your word is truth."

John 17:15–17

This is important to hear clearly. The prayer is not for escape. It is for protection in place, for holiness in the middle of the ordinary world, for truth to do its work in people who remain where they are. The disciples are not removed from danger; they are guarded through it.

He consecrates himself for their sake — sets himself apart for what is coming — so that they might be set apart in truth.

Those who will believe (verses 20–26)

Here the prayer opens past the eleven in the room.

"Not for these only do I pray, but for those also who will believe in me through their word, that they may all be one; even as you, Father, are in me, and I in you, that they also may be one in us; that the world may believe that you sent me."

John 17:20–21

Those who will believe through their word. The disciples would speak, and people would believe, and those people would speak, and others would believe — and the chain of witness reaches to this page. The prayer on the last night, in a room in Jerusalem, is a prayer about whoever is reading this now.

He wants them — us — to see his glory, the glory the Father gave him before the foundation of the world. He wants the world to know that the Father sent him and loves those who belong to him with the same love with which he loved the Son.

The prayer closes on a single phrase that contains the whole destination of the gospel:

"I made known to them your name, and will make it known; that the love with which you loved me may be in them, and I in them."

John 17:26

The love with which the Father loved the Son — the love that has existed before the world, between the eternal persons of God — he wants that love to be in us. Not directed toward us from a distance. In us. And he himself in us.

Take with you

The prayer moves through three circles: himself, his disciples, and all future believers. By the end of the chapter the circle has reached you.

The definition in verse 3 is worth returning to slowly. If eternal life is knowing the only true God — if it is relational and present, not only future — then eternal life is something that has already begun, or not yet begun, right now. The question the verse puts to the reader is not where will you spend eternity but do you know him?

The prayer for those who are in the world is also worth holding. Not taken out. Kept. Sanctified by truth. There is no prayer here for an easy road or an exit from the ordinary world. There is a prayer for people who stay in it and are protected and made holy in the middle of it.

And then the closing line. He prays that the love between Father and Son — the oldest, deepest love in existence — would be the love that lives in us. That is where John's gospel is heading: not just forgiveness, not just rescue, but the life of God himself made interior.
