John 14:25-31

These things have I spoken unto you, while yet abiding with you. 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.
