16:7 But I tell you the truth, it is to your advantage that I am going 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 concerning sin and righteousness and judgment – 16:9 concerning sin, because they do not believe in me; 16:10 concerning righteousness, because I am going to the Father and you will see me no longer; 16:11 and concerning judgment, because the ruler of this world has been condemned.

16:12 “I have many more things to say to you, but you cannot bear them now. 16:13 But when he, the Spirit of truth, comes, he will guide you into all truth. For he will not speak on his own authority, but will speak whatever he hears, and will tell you what is to come. 16:14 He will glorify me, because he will receive from me what is mine and will tell it to you.
