John 16:5-7
5 But now I go my way to him that sent me; and none of you asketh me, Whither goest thou?
6 But because I have said these things unto you, sorrow hath filled your heart.
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.
