Yochanan 16:7-13

But I tell HaEmes (the truth), it is better for you that I go away. For if I do not go away, the Melitz Yosher (Praklit, Advocate, Counselor, Helper in Court) will not come to you. But if go, I will send Him (the Ruach Hakodesh) to you. And having come, that one will expose and convict the Olam Hazeh concerning Chet and concerning Tzedek and concerning Mishpat: Concerning Chet (Sin), because they do not have emunah in me; Concerning Tzedek, because I go to HaAv and no longer do you see me; And concerning Mishpat (Judgment), because the Sar HaOlam Hazeh has been judged. Yet many things I have to tell you, but you are not able to bear them now. But when that One has come, the Ruach Hakodesh, the Ruach HaEmes, He will guide you in all truth. For He will not speak on His own authority, but what things He will hear, He will speak, and the things that are to come He will announce to you.
