John 16:7

4 But these things have I spoken unto you, that when their hour is come, ye may remember them, how that I told you. And these things I said not unto you from the beginning, because I was with you.

5 But now I go unto him that sent me; and none of you asketh me, Whither goest thou?

6 But because I have spoken these things unto you, sorrow hath filled your heart.

7 Nevertheless I tell you the truth: It is expedient for you that I go away; for if I go not away, the Comforter will not come unto you; but if I go, I will send him unto you.

8 And he, when he is come, will convict the world in respect of sin, and of righteousness, and of judgment:

9 of sin, because they believe not on me;

10 of righteousness, because I go to the Father, and ye behold me no more;
