John 15:26-27, 16:4b-11
26 “When the Advocate comes, whom I will send to you from the Father—the Spirit of truth who goes out from the Father—he will testify about me. 27 And you also must testify, for you have been with me from the beginning.
4b I did not tell you this from the beginning because I was with you, 5 but now I am going to him who sent me. None of you asks me, ‘Where are you going?’ 6 Rather, you are filled with grief because I have said these things. 7 But very truly I tell you, it is for your good that I am going away. Unless I go away, the Advocate will not come to you; but if I go, I will send him to you. 8 When he comes, he will prove the world to be in the wrong about sin and righteousness and judgment: 9 about sin, because people do not believe in me; 10 about righteousness, because I am going to the Father, where you can see me no longer; 11 and about judgment, because the prince of this world now stands condemned.”
