It really boils down to this: that all life is interrelated. We are all caught in an inescapable network of mutuality, tied to a single garment of destiny. Whatever affects one directly, affects all indirectly.
Gratitude is the vision of the Giver, not of the gift. It comes from God. Hope and fear are like the two wings of a bird when it is flying straight to its destination. If one wing fails, its flight fails and if both fail, it dies. Hope is the vision of God in perfect beauty.
