John 17 — Jesus' High Priestly Prayer for Unity
Jesus prays to the Father for glorification, eternal life through knowledge of God, the disciples' protection and sanctification, and the unity of all believers.
Scripture
1These things spake Jesus; and lifting up his eyes to heaven, he said, Father, the hour is come; glorify thy Son, that the son may glorify thee:
2even as thou gavest him authority over all flesh, that to all whom thou hast given him, he should give eternal life.
3And this is life eternal, that they should know thee the only true God, and him whom thou didst send, even Jesus Christ.
4I glorified thee on the earth, having accomplished the work which thou hast given me to do.
5And now, Father, glorify thou me with thine own self with the glory which I had with thee before the world was.
6I manifested thy name unto the men whom thou gavest me out of the world: thine they were, and thou gavest them to me; and they have kept thy word.
7Now they know that all things whatsoever thou hast given me are from thee:
8for the words which thou gavest me I have given unto them; and they received them, and knew of a truth that I came forth from thee, and they believed that thou didst send me.
9I pray for them: I pray not for the world, but for those whom thou hast given me; for they are thine:
10and all things that are mine are thine, and thine are mine: and I am glorified in them.
11And I am no more in the world, and these are in the world, and I come to thee. Holy Father, keep them in thy name which thou hast given me, that they may be one, even as we are.
12While I was with them, I kept them in thy name which thou hast given me: and I guarded them, and not one of them perished, but the son of perdition; that the scripture might be fulfilled.
13But now I come to thee; and these things I speak in the world, that they may have my joy made full in themselves.
14I have given them thy word; and the world hated them, because they are not of the world, even as I am not of the world.
15I pray not that thou shouldest take them from the world, but that thou shouldest keep them from the evil one.
16They are not of the world even as I am not of the world.
17Sanctify them in the truth: thy word is truth.
18As thou didst send me into the world, even so sent I them into the world.
19And for their sakes I sanctify myself, that they themselves also may be sanctified in truth.
20Neither for these only do I pray, but for them also that believe on me through their word;
21that they may all be one; even as thou, Father, art in me, and I in thee, that they also may be in us: that the world may believe that thou didst send me.
22And the glory which thou hast given me I have given unto them; that they may be one, even as we are one;
23I in them, and thou in me, that they may be perfected into one; that the world may know that thou didst send me, and lovedst them, even as thou lovedst me.
24Father, I desire that they also whom thou hast given me be with me where I am, that they may behold my glory, which thou hast given me: for thou lovedst me before the foundation of the world.
25O righteous Father, the world knew thee not, but I knew thee; and these knew that thou didst send me;
26and I made known unto them thy name, and will make it known; that the love wherewith thou lovedst me may be in them, and I in them.
What this passage means
Jesus opens by asking the Father to glorify the Son so that the Son may glorify the Father, framing the cross not as defeat but as the appointed 'hour' (verse 1) that reveals divine glory. Authority 'over all flesh' is given so that the Son can give eternal life to those the Father has entrusted to him (verse 2).
Eternal life is then defined relationally: 'that they should know thee the only true God, and him whom thou didst send, even Jesus Christ' (verse 3). Knowing is not mere information but covenant relationship with both Father and Son. Jesus then looks back on his finished earthly work (verse 4) and forward to the pre-creation glory he shared with the Father (verse 5).
The prayer turns to the disciples: Jesus asks the Father to keep them in his name (verse 11), sanctify them in the truth of the word (verse 17), and unite them as Father and Son are united (verses 21–23). The scope widens from the eleven to 'them also that believe on me through their word' (verse 20), so that the world's belief and knowledge of divine love rests on the visible unity of the community.
Context
The chapter is a single continuous prayer of Jesus spoken after the Last Supper discourse (cf. John 13–16) and before his arrest in John 18. The chapter note summarizes it as the 'high priestly prayer' centered on unity. Within the prayer Jesus moves from self (1–5), to the disciples present (6–19), to future believers (20–26), so the audience addressed by the prayer widens as it unfolds.
The theme of unity appears repeatedly: unity between Father and Son (verses 21, 22), unity among disciples (verse 11), and unity of all believers as the intended witness to the world (verse 23). Jesus does not ask for removal from the world but protection 'from the evil one' (verse 15), echoing his earlier teaching that believers remain in the world but are not 'of' it.
Key words in the original
- G2222 The Greek word ζωή (zōē) denotes 'life' in the sense of vital, divine life. In verse 3 Jesus uses it to define eternal life as relational knowledge of God rather than mere duration of existence.
- G0166 The adjective αἰώνιος (aiōnios), 'eternal/age-long,' modifies ζωή in verse 3. Within the context of this verse it frames eternal life as a present quality of knowing God rather than only a future duration.
- G1392 The verb δοξάζω (doxazō), 'to glorify,' frames the opening petition of the prayer (verse 1) and recurs through the chapter as mutual glorification between Father and Son. The provided context ties glory both to the cross and to the pre-creation state (verse 5).
Related verses
- 1 John 5:20 John's epistle echoes the chapter's definition of eternal life as knowing 'him that is true,' reinforcing the relational sense of γινώσκω in John 17:3.
- John 15:3 Jesus' earlier statement that the disciples are 'already... clean because of the word' forms a backdrop to the petition 'sanctify them in the truth: thy word is truth' in verse 17.
- Psalms 119:160 The Psalter's affirmation that 'the sum of thy word is truth' resonates with the prayer's identification of the Father's word with truth in verse 17, linking sanctification to the received word.
Common questions
Why does Jesus pray only for believers and not 'for the world' (verse 9)?
In context the prayer is for those given to Jesus by the Father; the world's salvation is the trajectory of the Son's mission (cf. John 3:17), but the specific intercession requested here is protection and unity for those entrusted to him. Jesus immediately distinguishes protection from removal (verse 15).
How does John 17 define eternal life?
Verse 3 defines eternal life as knowing 'the only true God, and him whom thou didst send, even Jesus Christ.' The provided context frames this knowing as relational rather than informational.
Why is unity between believers emphasized repeatedly?
Verses 21–23 link unity directly to the world's belief that the Father sent the Son and loved believers. In context the unity mirrors the unity between Father and Son, and is therefore both christological and missional in function.
