John 16:7-11

7 Nevertheless I tell you the truth: It is to your advantage that I go away, for if I don't go away, the Counselor won't come to you. But if I go, I will send him to you.  8 When he has come, he will convict the world about sin, about righteousness, and about judgment;  9 about sin, because they don't believe in me;  10 about righteousness, because I am going to my Father, and you won't see me any more;  11 about judgment, because the prince of this world has been judged.
