This letter is still being written, but its foundation is already set. Meditate on this while you wait for the full snapshot:

John 14:15-16

If you love me, you will keep my commandments. And I will ask the Father, and he will give you another Helper, to be with you forever, even the Spirit of truth, whom the world cannot receive, because it neither sees him nor knows him. You know him, for he dwells with you and will be in you.
