When the land is barren, it is empty, but it is not void.
The difference is that empty means there is nothing growing. Void means that there is no opportunity to grow anything.
Right now the land is empty. People are furloughed or laid off. Businesses are closed temporarily or permanently. But that also means that people are home and it is quiet. That means that there is now time to rest and consider next steps. That means that it is time to pray.
Prayers are seeds that go into the great universal field to be planted. Now is the time plant those seeds.
