Guardrails keep us on the pathway. They prevent us from falling off the cliff. They give us comfort that, though the paneling on our car may be damaged, if we slip on the icy road, yet we will not die.

A mountain road without those guardrails leaves us with a much greater fear. And that fear brings with it a greater pain. We experience that pain whether or not the worst happens, because we know there is a much higher likelihood that it will.
