To respect someone means to treat their ideas, personal space, belongings, and needs as equal in importance to your own, while to honor someone means to treat all those things as more important than your own.
Respect, Religion, Honor
The lesson is this: When the road gets dark and all hope seems lost, there's nothing to do but keep going. We, like Bilbo, must keep up our "hobbitry in heart." Even more important, as people of faith, we recognize that we are not alone. Whatever happens from this point on, we put our trust in God. And we go on.
Courage, Faith
