As we express our gratitude, we must never forget that the highest appreciation is not to utter words but to live by them. Let us therefore proclaim our gratitude to Providence for manifold blessings — let us be humbly thankful for inherited ideals — and let us resolve to share those blessings and those ideals with our fellow human beings throughout the world.
