John 14:26-30

But the Helper will teach you everything and will cause you to remember all that I told you. This Helper is the Holy Spirit whom the Father will send in my name. “I leave you peace; my peace I give you. I do not give it to you as the world does. So don’t let your hearts be troubled or afraid. You heard me say to you, ‘I am going, but I am coming back to you.’ If you loved me, you should be happy that I am going back to the Father, because he is greater than I am. I have told you this now, before it happens, so that when it happens, you will believe. I will not talk with you much longer, because the ruler of this world is coming. He has no power over me
