John 16

7 But I say the truth to you, It is profitable for you that I go away; for if I do not go away, the Comforter will not come to you; but if I go I will send him to you. 8 And having come, he will bring demonstration to the world, of sin, and of righteousness, and of judgment: 9 of sin, because they do not believe on me; 10 of righteousness, because I go away to my Father, and ye behold me no longer; 11 of judgment, because the ruler of this world is judged.
