16:6. But because I have spoken these things to you, sorrow hath filled your heart.
16:7. 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.
16:8. And when he is come, he will convince the world of sin and of justice and of judgment.
He will convince the world of sin, etc.... The Holy Ghost, by his coming brought over many thousands, first, to a sense of their sin in not believing in Christ. Secondly, to a conviction of the justice of Christ, now sitting at the right hand of his Father. And thirdly, to a right apprehension of the judgment prepared for them that choose to follow Satan, who is already judged and condemned.
16:9. Of sin: because they believed not in me.
16:10. And of justice: because I go to the Father: and you shall see me no longer.
16:11. And of judgment: because the prince of this world is already judged.
16:12. I have yet many things to say to you: but you cannot bear them now.
16:13. 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.
Will teach you all truth.... See the annotation on chap. 14. ver. 26.
