John 16:7-9

Young's Literal Translation

⁷ `But I tell you the truth; it is better for you that I go away, for if I may not go away, the Comforter will not come unto you, and if I go on, I will send Him unto you;

⁸ and having come, He will convict the world concerning sin, and concerning righteousness, and concerning judgment;

⁹ concerning sin indeed, because they do not believe in me;
