The point of passing time in solitude is to strip yourself bare, to discover what is essential and true. When you are stripped down to this point, you see how little you amount to. But that little is what God is interested in.
We need to sit still, let our emptiness remain empty, and wait patiently. If we fill the foreground with busy questions, reasons or proposed actions, we will miss the God who is the silent, yet ever present horizon of the world.
