Shared ground
Jesus ends his prayer by naming what he wants: the people the Father has given him will be with him “where I am” and will see his “glory” (explicit). That hope is grounded in the Father’s prior love for the Son “before the foundation of the world” (explicit), which points to a relationship that predates Jesus’ public ministry.
He also draws a contrast about “knowing” God: “the world” did not know the Father, Jesus did know the Father, and “these” (his followers) came to know that the Father sent Jesus (explicit). In this passage, “know” is not just having information; it is recognition of who Jesus is in relation to the Father (inference from the stated contrast and “sent me”).
Finally, Jesus says he has made the Father’s “name” known and will continue to make it known, with the stated aim that the Father’s love will be “in them,” and that Jesus will be “in them” (explicit).
Where interpretation differs (only where needed)
1) What “where I am” refers to. Some read it mainly as Jesus’ presence with the Father after his death and resurrection, implying a future “being with” him. Others think it includes Jesus’ present reality and mission even before the cross, so “be with me” can also mean sharing his life and path now, not only later.
2) What it means to “see my glory.” Some take “glory” here as Jesus’ visible honor in his final revelation (resurrection/exaltation and ultimate unveiling). Others emphasize that in John, Jesus’ “glory” is already displayed in the cross and the love revealed there, so “seeing” can include perceiving that meaning, not only a future sight.
3) Who “the world” is. Some hear “world” as humanity as a whole in its general failure to know God. Others hear it more specifically as the surrounding order that resists Jesus and does not recognize the Father through him.
4) What “I in them” describes. Some understand it mainly as Jesus’ personal presence shared with believers (real but not physical). Others connect it closely to Jesus’ continued self-disclosure through his message and the Father’s love, so “in them” highlights relational indwelling expressed through shared knowledge, love, and allegiance.
Why the disagreement exists
John uses short phrases with big theological reach (“where I am,” “glory,” “world,” “name,” “in them”). The immediate context does not spell out a timeline, and John elsewhere speaks of glory, presence, and “world” in more than one way. Readers therefore weigh different nearby themes (cross, resurrection, exaltation, ongoing revelation) when deciding what is foregrounded here.
What this passage clearly contributes
This closing ties together Jesus’ mission and his intended outcome: (1) Jesus’ followers ultimately belong with him and are meant to behold his Father-given glory; (2) knowing the Father is bound to recognizing Jesus as the one sent; (3) Jesus’ work of making God known is not described as finished at this moment (“will make it known”); and (4) the stated goal of that ongoing disclosure is shared love—“the love” the Father has for the Son—and Jesus’ continuing presence “in them.” It reinforces that relationship (knowing, love, presence) is central to the chapter’s ending, not only protection or unity.
