I recently heard someone say that everything about the world has been making them lose their faith in it. For me, despite all of the frustrations I have, I feel the opposite. I see goodness, joy, and beauty all around us. Even in dire situations, I see determination and even love. I see God's hand supporting, comforting, and inspiring. Sure, I suppose that it's possible to focus on the negative and see it everywhere, but I prefer to see it as the contrast to what is good.
God is calling us to be witnesses to the goodness of His creation, but also to be part of that goodness and to make the world a better place.
