John 15:26-27; 16:4b-15
15:26 "When the Advocate comes, whom I will send to you from the Father, the Spirit of truth who comes from the Father, he will testify on my behalf.

15:27 You also are to testify because you have been with me from the beginning.

16:4b "I did not say these things to you from the beginning, because I was with you.

16:5 But now I am going to him who sent me; yet none of you asks me, 'Where are you going?'

16:6 But because I have said these things to you, sorrow has filled your hearts.

16:7 Nevertheless I tell you the truth: it is to your advantage that I go away, for if I do not go away, the Advocate will not come to you; but if I go, I will send him to you.

16:8 And when he comes, he will prove the world wrong about sin and righteousness and judgment:

16:9 about sin, because they do not believe in me;

16:10 about righteousness, because I am going to the Father and you will see me no longer;

16:11 about judgment, because the ruler of this world has been condemned.

16:12 "I still have many things to say to you, but you cannot bear them now.

16:13 When the Spirit of truth comes, he will guide you into all the truth; for he will not speak on his own, but will speak whatever he hears, and he will declare to you the things that are to come.

16:14 He will glorify me, because he will take what is mine and declare it to you.

16:15 All that the Father has is mine. For this reason I said that he will take what is mine and declare it to you.
