St John 16:10-13, 7-9

And of justice: because I go to the Father; and you shall see me no longer. And of judgment: because the prince of this world is already judged. I have yet many things to say to you: but you cannot bear them now. But when he, the Spirit of truth, is come, he will teach you all truth. For he shall not speak of himself; but what things soever he shall hear, he shall speak; and the things that are to come, he shall shew you.

But I tell you the truth: it is expedient to you that I go: for if I go not, the Paraclete will not come to you; but if I go, I will send him to you. And when he is come, he will convince the world of sin, and of justice, and of judgment. Of sin: because they believed not in me.
