When Hashem created the world, He would not send the rains until there was a person on this earth who would appreciate this gift and and be grateful for it. Adam prayed for rain. It fell. Trees and vegetation grew. And Adam thanked Hashem. It was necessary, as soon as man was created, to teach him the lesson of gratitude  because gratitude makes all the difference between a life that is happy and fulfilling, and one that is sad and bitter. Let There Be Rain, by Rabbi Wallerstein with bestselling author Rabbi Shimon Finkelman, combines Torah wisdom with marvelous stories to show us how to incorporate hakaras hatov into our thoughts, hearts and actions. It offers a daily reading that includes an informative Torah insight and an inspiring story to illustrate the concept.
