Charles Spurgeon Commentary John 16:7-9

"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 go, I will send him unto you. And he, when he is come, will convict the world in respect of sin, and of righteousness, and of judgment: of sin, because they believe not on me;" — John 16:7-9 (ASV)

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. And when he is come, he will reprove the world of sin, and of righteousness, and of judgment: Of sin, because they believe not on me;

Which is the head of all sin, the root of all sin, the sin which lies in front of the door of mercy, and blocks the sinner's way. Oh, that the Spirit of God would convince all here, who are not believers on the Lord Jesus Christ, that they are living in the greatest of all sins because they believe not on Christ!
