John 17:15 — Kept from the Evil One, Not Taken from the World
Jesus prays that the Father would keep His disciples from the evil one while leaving them in the world to carry out the mission they were sent into it to do.
Scripture
15I pray not that thou shouldest take them from the world, but that thou shouldest keep them from the evil one.
What this passage means
John 17:15 sits at the center of the High Priestly prayer. The petition is negative twice over — "I pray not that thou shouldest take them from the world, but that thou shouldest keep them from the evil one" — and the structure matters. Jesus first names what He is not asking for: removal from the κόσμου (the ordered world in which the disciples have been placed). Then He names what He is asking for: protection ἐκ τοῦ πονηροῦ, out from under the active influence of the evil one. The two halves are not interchangeable; the first clarifies the scope of the second.
The verse connects backward to verse 14, where Jesus noted that the world has already hated the disciples because they are not of the world, even as Jesus is not of the world. The hostility is established as a fact; the request is not escape from the hostile environment but preservation within it. It also connects forward to verse 18, where the same ἐκ τοῦ κόσμου / εἰς τὸν κόσμον movement is repeated: as the Father sent Jesus into the world, so Jesus sends them. The prayers bracketing the petition — for unity (17:11), for preservation (17:15), for sanctification in truth (17:17) — together describe what continued mission in a hostile world requires.
The Greek verb τηρήσῃς (from τηρέω) is a guarding word, defined in the lexical entry as watching over so that nothing is lost or injured. The prayer is therefore not for immunity from hardship but for custody under hostile conditions. The disciples remain in the world because they have been sent into it; they are kept so that the sending is not undone.
Context
John 17 is the High Priestly prayer. Verses 1–5 set Jesus' own glorification before the Father; verses 6–19 turn to the disciples Jesus is about to leave in the world. The chapter note for John 17 identifies the prayer as a prayer for unity, and 17:15 is one petition within that longer request. The chapter's own framing in 17:9, 17:13, 17:18, 17:20–23 makes clear that the prayer is for disciples who remain in the world and continue a sending.
In the immediate vicinity, 17:14 records the world's hatred, 17:16 echoes 17:14 with "they are not of the world even as I am not of the world," and 17:17–19 widens the request to sanctification in the truth and Jesus' own self-sanctification for their sake. Verse 15 is therefore the pivot between the diagnosis of the disciples' situation (hated, not of the world) and the provisions made for them (kept, sent, sanctified).
Key words in the original
- G5083 τηρέω — to guard, watch over so that nothing is lost or injured. The lexical entry contrasts it with terms for preventing escape and for fortress-style military guarding; here it frames protection as custody, not extraction.
- G4190 πονηρός — the evil one. The lexical entry distinguishes it from terms for general evil character or for degenerate corruption; here it is the active moral adversary behind the world's hostility described in 17:14.
- G2889 κόσμος — the ordered world. The lexical entry defines it broadly as the orderly arrangement that includes its inhabitants. In 17:15 Jesus does not pray for the disciples' removal from this world, because their mission (17:18) requires their presence in it.
Related verses
- Psalms 121:7 Jehovah will keep thee from all evil. The Septuagint wording of Ps 121:7 uses cognate terms for keeping and evil, providing the OT background for Jesus' petition that the Father guard the disciples from the evil one.
- 2 Thessalonians 3:3 the Lord is faithful, who shall establish you, and guard you from the evil one. Paul echoes the same petition in epistolary form, applying to the Thessalonian church the protective request Jesus made for the first disciples.
- 1 John 5:18 he that was begotten of God keepeth himself, and the evil one toucheth him not. The Johannine epistle reflects the same posture — the evil one is named as the active adversary, and the believer's preservation is treated as a present reality.
Common questions
Why does Jesus not ask the Father to take the disciples out of the world?
Because the disciples have been sent into the world for a mission (17:18). The chapter note identifies John 17 as a prayer for unity tied to that sending; removing them from the world would undo the purpose for which they were given to Jesus (17:9).
Does "the evil one" refer to a person or to evil in general?
The Greek πονηρός in 17:15 is articular ("the evil one"), and the lexical entry distinguishes it from general terms for evil character or degeneration. Read alongside 17:14's personal hostility of the world, the passage presents the evil one as an active moral adversary opposed to the disciples.
How does this verse relate to the Lord's Prayer in Matthew 6:13?
Both are prayers addressed to the Father asking for deliverance from the evil one. The cross-references list both Matthew 6:13 and Luke 11:4 as parallel petitions; Jesus' wording in John 17:15 reflects the same vocabulary the disciples had been taught to use.
