This world was created lacking. That's the way it's meant to be. This world strives to arrive somewhere beyond itself for its completion. However its completion can come only from above, from Heaven. This world contains many wonderful things, but perfection isn't one of them.
Perfection is beyond the scope of creation.
This is why G-d's name is Shalom. G-d is the Perfection of all the lacking of this world. Every single thing in this world finds its perfection, its fulfillment, in Him. It's not here. In the Book of Ruth, Boaz greets the harvesters by using the name of G-d.
