First Jesus said, "Nevertheless I tell you the truth; It is expedient for you that I go away: for if I go not the Comforter will not come unto you. And when He is come He will reprove the world of sin, and of judgement. Of sin, because they believe not on me. Of righteousness, because I goto the Father, and ye see me no more; I have many things to say to you but you cannot bare them now. Howbeit when He, then Spirit of truth, is come, He will guide you into all truth: for He shall not speak of Himself but whatsoever He shall hear, that shall He speak: and He will show you things to come. John 16:7 to 13.
