Have you ever felt God? Has there ever been a time, where in your sincerest opinion, you felt a presence of God- not just as a concept but as an actual being? It could have been a very dramatic time where you literally heard the voice of God, etc. You could have felt than and forgotten it, or discounted the significance.
If you can say yes to that, then you already have what you need. We are all isolated. It's a part of the system of control. But we aren't alone.
