[15:8] 1 tn Grk “glorified.”
[15:8] 2 tn The ἵνα (Jina) clause is best taken as substantival in apposition to ἐν τούτῳ (en toutw) at the beginning of the verse. The Father is glorified when the disciples bring forth abundant fruit. Just as Jesus has done the works which he has seen his Father doing (5:19-29) so also will his disciples.
[15:8] 3 tn Or “yield.”
[15:8] 4 tc Most mss (א A Ψ Ë13 33 Ï) read the future indicative γενήσεσθε (genhsesqe; perhaps best rendered as “[and show that] you will become”), while some early and good witnesses (Ì66vid B D L Θ 0250 1 565 al) have the aorist subjunctive γένησθε (genhsqe; “[and show that] you are”). The original reading is difficult to determine because the external evidence is fairly evenly divided. On the basis of the external evidence alone the first reading has some credibility because of א and 33, but it is not enough to overthrow the Alexandrian and Western witnesses for the aorist. Some who accept the future indicative see a consecutive (or resultative) sequence between φέρητε (ferhte) in the ἵνα (Jina) clause and γενήσεσθε, so that the disciples’ bearing much fruit results in their becoming disciples. This alleviates the problem of reading a future indicative within a ἵνα clause (a grammatical solecism that is virtually unattested in Attic Greek), although such infrequently occurs in the NT, particularly in the Apocalypse (cf. Gal 2:4; Rev 3:9; 6:4, 11; 8:3; 9:4, 5, 20; 13:12; 14:13; 22:14; even here, however, the Byzantine mss, with א occasionally by their side, almost always change the future indicative to an aorist subjunctive). It seems more likely, however, that the second verb (regardless of whether it is read as aorist or future) is to be understood as coordinate in meaning with the previous verb φέρητε (So M. Zerwick, Biblical Greek §342). Thus the two actions are really one and the same: Bearing fruit and being Jesus’ disciple are not two different actions, but a single action. The first is the outward sign or proof of the second – in bearing fruit the disciples show themselves to be disciples indeed (cf. 15:5). Thus the translation followed here is, “that you bear much fruit and show that you are my disciples.” As far as the textual reading is concerned, it appears somewhat preferable to accept the aorist subjunctive reading (γένησθε) on the basis of better external testimony.
[17:4] 5 tn Or “by finishing” or “by accomplishing.” Jesus now states that he has glorified the Father on earth by finishing (τελειώσας [teleiwsas] is best understood as an adverbial participle of means) the work which the Father had given him to do.
[17:4] sn By completing the work. The idea of Jesus being sent into the world on a mission has been mentioned before, significantly in 3:17. It was even alluded to in the immediately preceding verse here (17:3). The completion of the “work” the Father had sent him to accomplish was mentioned by Jesus in 4:34 and 5:36. What is the nature of the “work” the Father has given the Son to accomplish? It involves the Son’s mission to be the Savior of the world, as 3:17 indicates. But this is accomplished specifically through Jesus’ sacrificial death on the cross (a thought implied by the reference to the Father “giving” the Son in 3:16). It is not without significance that Jesus’ last word from the cross is “It is completed” (19:30).
[17:4] 6 tn Grk “the work that you gave to me so that I may do it.”
