John 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. 8 And when he is come, he will convince the world of sin, and of justice, and of judgment. 9 Of sin: because they believed not in me. 10 And of justice: because I go to the Father; and you shall see me no longer.
8 “He will convince the world of sin”… 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.
