John 16:7-11

16:7 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. 16:8 And when he is come, he will reprove the world of sin, and of righteousness, and of judgment: 16:9 Of sin, because they believe not on me; 16:10 Of righteousness, because I go to my Father, and ye see me no more; 16:11 Of judgment, because the prince of this world is judged.

John 16:33

16:33 These things I have spoken unto you, that in me ye might have peace. In the world ye shall have tribulation: but be of good cheer; I have overcome the world.
