John 16:8 ASV

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;
