[16:9] 1 tn Or “that.” It is very difficult to determine whether ὅτι (Joti; 3 times in 16:9, 10, 11) should be understood as causal or appositional/explanatory: Brown and Bultmann favor appositional or explanatory, while Barrett and Morris prefer a causal sense. A causal idea is preferable here, since it also fits the parallel statements in vv. 10-11 better than an appositional or explanatory use would. In this case Jesus is stating in each instance the reason why the world is proven guilty or wrong by the Spirit-Paraclete.
[16:9] 2 sn Here (v. 9) the world is proven guilty concerning sin, and the reason given is their refusal to believe in Jesus. In 3:19 the effect of Jesus coming into the world as the Light of the world was to provoke judgment, by forcing people to choose up sides for or against him, and they chose darkness rather than light. In 12:37, at the very end of Jesus’ public ministry in John’s Gospel, people were still refusing to believe in him.
[16:10] 3 tn There are two questions that need to be answered: (1) what is the meaning of δικαιοσύνη (dikaiosunh) in this context, and (2) to whom does it pertain – to the world, or to someone else? (1) The word δικαιοσύνη occurs in the Gospel of John only here and in v. 8. It is often assumed that it refers to forensic justification, as it does so often in Paul’s writings. Thus the answer to question (2) would be that it refers to the world. L. Morris states, “The Spirit shows men (and no-one else can do this) that their righteousness before God depends not on their own efforts but on Christ’s atoning work for them” (John [NICNT], 699). Since the word occurs so infrequently in the Fourth Gospel, however, the context must be examined very carefully. The ὅτι (Joti) clause which follows provides an important clue: The righteousness in view here has to do with Jesus’ return to the Father and his absence from the disciples. It is true that in the Fourth Gospel part of what is involved in Jesus’ return to the Father is the cross, and it is through his substitutionary death that people are justified, so that Morris’ understanding of righteousness here is possible. But more basic than this is the idea that Jesus’ return to the Father constitutes his own δικαιοσύνη in the sense of vindication rather than forensic justification. Jesus had repeatedly claimed oneness with the Father, and his opponents had repeatedly rejected this and labeled him a deceiver, a sinner, and a blasphemer (John 5:18, 7:12, 9:24, 10:33, etc.). But Jesus, by his glorification through his return to the Father, is vindicated in his claims in spite of his opponents. In his vindication his followers are also vindicated as well, but their vindication derives from his. Thus one would answer question (1) by saying that in context δικαιοσύνης (dikaiosunh") refers not to forensic justification but vindication, and question (2) by referring this justification/vindication not to the world or even to Christians directly, but to Jesus himself. Finally, how does Jesus’ last statement in v. 10, that the disciples will see him no more, contribute to this? It is probably best taken as a reference to the presence of the Spirit-Paraclete, who cannot come until Jesus has departed (16:7). The meaning of v. 10 is thus: When the Spirit-Paraclete comes he will prove the world wrong concerning the subject of righteousness, namely, Jesus’ righteousness which is demonstrated when he is glorified in his return to the Father and the disciples see him no more (but they will have instead the presence of the Spirit-Paraclete, whom the world is not able to receive).
