The setting for the discourse in this chapter and the following chapter appears to be in Jerusalem. The precise location is not specified, but John 18:1 states that afterwards, "Jesus left with his disciples and crossed the Kidron Valley".
Purpose
The evangelist's purpose in this section of his gospel is to support the early Church for whom he is writing, to ensure that they do not fall away (Greek: ινα μη σκανδαλισθητε, hina mē skandalisthēte) (John 16:1). Some commentators suggest he is writing for a specific group of believers called the Johannine Community.[4]
Verse 1
All this I have told you so that you will not fall away.[5]
Heinrich Meyer relates "all this" to John 15:18–27, the section of this discourse which anticipates the world's hatred for the disciples.[6]
English translations vary widely in the way they treat the opening verse of this chapter:
Prepared beforehand, and armed by Christ’s communications, they were not to be made to stumble at Him, but were to oppose to the hatred of the world all the greater efficiency and constancy of faith.[6]
William Robertson Nicoll comments that the disciples' failure to ascertain clearly where Jesus was going reflected their absorption with "the thought of His departure and its consequences of bereavement [for] themselves".[13]
Verses 8-11
Commentator Henry Alford refers to three key words in this chapter, ἁμαρτία, δικαιοσύνη, κρίσις (sin, righteousness and judgment, John 16:8–11) which "comprehend the three great steps of advance in spiritual truth among men".[14]
Verse 13
However, when He, the Spirit of truth, has come, He will guide you into all truth; for He will not speak on His own authority, but whatever He hears He will speak; and He will tell you things to come.[15]
Alford advises that in the words all truth, "no promise of universal knowledge, nor of infallibility, is hereby conveyed; but a promise to them and us, that the Holy Spirit shall teach and lead us, not as children, under the tutors and governors of legal and imperfect knowledge, but as sons".[14]
Verse 24
Until now you have asked nothing in My name. Ask, and you will receive, that your joy may be full.[16]
