John 14: 27 - 31
27 Peace I leave with you; my peace I give to you; not as the world gives do I give to you. Let not your hearts be troubled, neither let them be afraid.
28 You heard me say to you, `I go away, and I will come to you.' If you loved me, you would have rejoiced, because I go to the Father; for the Father is greater than I.
29 And now I have told you before it takes place, so that when it does take place, you may believe.
30 I will no longer talk much with you, for the ruler of this world is coming. He has no power over me;
31 but I do as the Father has commanded me, so that the world may know that I love the Father. Rise, let us go hence.
