John 14:18, 26-27

No, I will not abandon you as orphans—I will come to you.

But when the Father sends the Advocate as my representative—that is, the Holy Spirit—he will teach you everything and will remind you of everything I have told you. “I am leaving you with a gift—peace of mind and heart. And the peace I give is a gift the world cannot give. So don’t be troubled or afraid.
