Beresheit Rabbah (3:7) teaches that God created and destroyed many worlds before finally allowing this world, our world, to stand. This midrash is teaching us three things. First, destruction and loss are a part of the fabric of our very existence. There is no avoiding it; there is only wrestling and reconciling and accepting it. Second, the midrash contains in it a promise or a hope that even after each destruction, a new world is created. After loss, there is rebirth. After the destruction of one world, there is the creation of the next.
