John 14:26-31

But the Comforter, even the Holy Spirit, whom the Father will send in my name, he shall teach you all things, and bring to your remembrance all that I said unto you. Peace I leave with you; my peace I give unto you: not as the world giveth, give I unto you. Let not your heart be troubled, neither let it be fearful. Ye heard how I said to you, I go away, and I come unto you. If ye loved me, ye would have rejoiced, because I go unto the Father: for the Father is greater than I. And now I have told you before it come to pass, that, when it is come to pass, ye may believe. I will no more speak much with you, for the prince of the world cometh: and he hath nothing in me; but that the world may know that I love the Father, and as the Father gave me commandment, even so I do. Arise, let us go hence.
