I read this amazing book last year called The Hidden Life of Trees by Peter Wohlleben about how trees that are connected to each other can help and protect each other through their connections, and how a single tree off by itself doesn't have the same protections.
There are so many hidden things happening in people, too. We can have a tiny effect on a lot of people, and those effects can build and build in a domino effect. The very small kindnesses we do for each other — a smile, a nod, opening a door — can make the world a better place. The prayers we say for each other — friend or stranger — can have unknown positive effects. Just because we don't know if our efforts will bear fruit doesn't mean we shouldn't try.
I hope you find these encouraging words food for thought today.
