John 16:7

4 But these things have I told you, that when the time shall come, ye may remember that I told you of them. And these things I said not unto you at the beginning, because I was with you.

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

6 But because I have said 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 depart, I will send him unto you.

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

9 Of sin, because they believe not on me;

10 Of righteousness, because I go to my Father, and ye see me no more;
